Twistin: Where is the difference? Take The Settlers. This game exists for Amiga and PC. The Amiga version is the worst one, that's for sure. Now "why create all the hoopla over it"? The answer is simple: why not? And it is the same with CGA games. And it is already the same with first-generation FPS. And it will be the same with more current games.
Personally, I absolutely agree with the reasoning you show here (I can't understand people praising CGA games, I can't understand people drooling over 3D shooters and I can't understand people raving about new games) - it is exactly the same things I always hear from arrogant PC users and also (in reference to the last paragraph) what I'm saying myself. I don't think however dismissing their point of view is a really good behaviour.
