PCs for home gaming
You mention Doom, which wasn't even an issue until the waning days of AGA in the mid 90s period, after which much of the damage to the Amiga brand through lack of chipset development for 8 years had already affected EU sales. Doom also is a 100% designed for PC thing, powerful CPU used to do everything and no custom chips, total opposite of Amiga and SNES/Sega consoles.
That's because the PC had access to a powerful CPU, and the ability to upgrade them.
You can't really upgrade your sega's CPU. That's why DOOM for sega 32x blew.
You also mention VGA but a default VGA graphics option in PC arcade games certainly didn't happen until the early 90s circa 1991/92, hell even Cinemaware didn't support them before that, very few games were VGA. EGA (ie C64 look-a-like colour palette graphics) games where the PC norm for the entire 80s.
The early 90s is when Amiga started to lose its footing, isn't it?

No more dopey Atari DOS games with bleepblooping and crapass colors (which played perfectly fine to be honest)! There were plenty of DOS classics. What planet are you on here dude?
Anyway, in the 90s You'd have access to stuff like Doom, Wing Commander, Duke Nukem, World of Xeen, and Ultima VII... and Soundblaster, Adlib? MT-32..... mmmm

. To think VGA wasn't part of the success of the PC would be clueless.
You can't sell a man an A1000 if he has just spent $1500 on an EGA PC, and that's just a fact of life.
Sure you can. Ask my Uncle. he had 2 Amigas, and a few PCs.
FM sounds vs 8bit DAC
You're missing the point, with the TG or Genesis soundchip (and every other computer and console of the time) you are stuck with the specific sound producing capabilities to produce your music in the style of that chip. So you have a unique 'style' of sound whether you like it or not. You can't play piano sounds on an acoustic guitar, but you can play both sounds on a Sinclavia or Fairlight sampling synthesizer of the early/mid 80s, this was the reason for utilising 4 8bit DACs as your sound chip in 1982/83 when the design was being drawn up and prototyped.
I don't think you even have a point. You can sample on the Turbo Grafx. 6 Channels of sampled sound. That is more than the Amiga. The thing also has stereo panning, which makes it even better than the Amiga, right?
Someone was even batshit crazy enough to make it play MOD and XMs. You can sample on the Genesis too.
Though this doesn't really matter, because even a standardized sound chip when used right can produce some nice music, and when you are looking for an arcade experience, you'll find that FM/PSG more accurately recreates it, seeing as that's whats in the arcades...
Also, for the record, sampled guitars blow. I would take 32-byte PSG music over corny sampled guitars like in Menace on Amiga...
Taking your argument even further....an Intel i7 at maximum production CPU speed sold by Intel can not replicate perfectly the sound of a C64 sound chip, it doesn't matter. You were missing the point, the Amiga had 4 channels of 'make any kind of sound you like and do whatever you want with it volume and frequency wise'. So my point was simply that the Amiga sound system only had one down side compared to say the Genesis FM chip, and that was total number of sound channels. If you actually want those kind of basic fixed waveform sounds of Genesis/TG/NES then great, but if you want to replicate some of the MOD tunes from Amiga like the Revelations slideshow demo by Cryptoburners though then forget it, unless you happen to have that 'instrument' built in on the bespoke sound chip. But you don't because you can't compete with a sampler+stack of CDs for versatility, no sound chip in the world could. That was the down side of every other machine.
All of the old sound chips are emulated good enough today that you can't really tell the difference. If you say you can, I say you're lying and being a spaz.
Like I said, sampling is able to be done on the TG and the Genesis, rendering alot of this argument useless.
Not to mention, another nice little thing is the Turbo Grafx CD, and the Sega CD. No amount of "make it sound like you want" sampling setup can cope with redbook audio.

Rental feasibility, Cart vs 3.5" floppy I doubt you would snap a 3.5" disk in half by accident, and it's not going to get damaged by accident. To be honest 3.5" floppy disks are very sturdy as a piece of plastic design unlike 5.25" disks like on the x68000, certainly sturdy enough to be dropped from standing up height sure. And dropping a disk in a mug of water/soup is no less a problem than dropping a cart in it. So magnetic destruction is the only real issue and even leaving disks on PSUs and large hifi speakers I have never lost a disk like that, only had bad disks if I bought unbranded crap disks for peanuts.
Christ you are dense. I can take a 3.5" floppy and crack it to pieces with one hand. Try doing that to a sega game. Not gonna work unless you're Lou Ferrigno.
And, you can get cartridges wet and they still work. as long as you let them dry out and they don't corrode, you're fine. Disks, not so much.
Virus? Simple, remove the write enable tab from the disks leaving them permanently wite protected, it's not like there were any arcade games that wrote back to the disk as a requirement and it's no different technically to the tab being broken on rental tapes to stop dumdums recording over a film with the superbowl!
Simple he says! You act like virus-spreaders are braindead and not crafty at all.
Hell I wouldn't be surprised if someone somewhere dismantled a floppy disk, put a new one in place that loaded up some porno on your Amiga, and then re assembled it and sold it to some little kid.
I suspect the reason blockbusters didn't rent Amiga games was due to a smaller market, and possibly as they would need to get an individual legal agreement with every single software company that sold Amiga games they wanted to rent out. It's not as simple as when they just did a single deal with Sega and Nintendo.
I suspect it is because giving floppies out to the general public and expecting them to come back in 1 piece every time is mental. You never know a floppy game is borked til you try to load the borked part.
And usability certainly isn't the issue, if you are too stupid to pop 'Disk 1' in your A500, out of a maximum of 2 or 3 on average for Amiga arcade games, and flick the switch on the PSU you then evolution dictates you shouldn't even be allowed to procreate! We are not talking about epic arcade point and click adventures from Lucas Arts on 12 disks here!
Why arent we talking about them? Do you think rental places only rent out durpy arcade games?
Useability is an issue. For one, what if the game requires something that you are unsure if your Amiga has? What if your parents aren't computer experts and you're like, 10.
It's easier to go "MMM SONIC" and grab it off the shelf and go home, knowing it will work in your Sega. a genesis is a genesis. They are all the same. No chip ram expansions, or crap like that.
Off-topic personal opinions about game comparisons
For every NES game you show that is worse as a C64 conversion I can show you 1 of superior conversion. If you are a Mario fanboy then you have to own a Nintendo. How many games did NES have? 750? That's between 5-10% of the C64/Amiga catalogue.
Do it. I can't wait to see what biased nonsense occurs.

Are you going to tell me the Salamander for C64 is better? That will be funny.
Anyway we are talking about Amiga, NOT C64 games, which were 6x cheaper than the tiny and repetitive catalogue of the NES.
Then why are we talking about NES? It holds nothing to the Amiga. Duh.
Genesis struggled to produce a superior version of Lotus challenge II compared to Amiga BUT Lotus II on Genesis is not really that different in speed and quality of animation to Genesis version of Outrun, so you can't go crying about one game being badly coded. So therefore clearly the Amiga version of Outrun should have been pretty damned close to the Genesis version which is really nice rather than that steaming turd US Gold produced.
Lotus Challenge 2 sucks, so its ok.
and, the rest of that quote makes no sense. It's too full of attempted higher English. So, thus, therefore clearly rather I got bored reading it. :roflmao:
was designed around PC architecture, just like Shadow of the Beast was designed around the Amiga OCS chipset. Both games only work well on the intended target machine, but this is 100% off topic and not really relevant to the discussion anyway.
The PCE CD version of Shadow of the Beast plays and sounds better than the Amiga one.
Just sayin.
