Concerning Sim City 2000 I've only got one advice: use ShapeShifter together with the free MacOS and run Sim City 2000 there. You won't believe how much faster it is! A shame, that emulating the Mac running Sim City 2000 is so much faster than playing the AMiGA version on the very same computer. Shame on Maxis. Shame.
Concerning great AMiGA games, AGA or no AGA: the thing I'm most frustrated about is that the programmers seemed to know nothing of 50 or 60 Hz smooth scrolling. Look at Turrican II (superb scrolling). Then look at Chaos Engine AGA (ugly scrolling). Look at Superfrog (superb scrolling). Then look at Project X (good scrolling but bad updates of the sprites).
Games tend to age so extremely fast when they don't have smooth scrolling. Project X runs smooth, the srcolling of the level, but the enemies are updated at 25/30 FPS. Look dead ugly. And Chaos Engine, like 20-25 FPS. What's that all about? It's not like it is too advanced to not run in full 50/60.
Ruff'n'Tumble. Heard so much about it. Started it and played it for like 2 minutes then turned off the computer. Could the scrolling possibly be any worse? Even though the game may be good, like I was told, the presentation was so dreadful I can't understand how they ever got around releasing it in the first place.
Oh well. That's the way it was. I guess. I just can't understand it. Shame. Shame. Shame.
