I remember when I finally got my first Amiga in the mid 90's.
On the one hand I was seriously disappointed in many of the Arcade to Amiga conversions in comparison to their Sega Master System, NES, Genesis, and SNES counter parts.
It never failed that the Amiga got the short end of the stick in that territory considering that the Japanese were only in the business of Consoles in the American market.
As for U.S. programmers, they seemed to stick primarily with the 8-Bit Machines, and PC during the 80's, though there were a few exceptions.
Another thing that always irritated me about the Amiga as well as the Atari 8-bit Computer was the fact that they were one button centric. I HATE having to reach out and press the space bar for my second button. Too bad a Joyhack was never made that could resolve that.
(thankx for the list Cammy, I didn't realize there were so many)
Now back to the US Consoles, I always felt like their ports were lacking, or that they neglected to port some of the best titles. It wasn't until the Sega CD version of Forgotten Worlds came out that I finally played an Arcade port that seemed PERFECT to it's Arcade original on any system. Though now thankfully we have MAME which has satisfied me with all of my Arcade lust with the exception of Star Wars Trilogy Arcade. Drooooolllll!
