Nazobyte, I am afraid that I have to disagree; when I had ME installed on my computer, I had NOTHING but trouble. In fact, it was such a disaster that I had to revert back to 98SE! And when it comes to gaming on ME, you can just forget about it, with constant compatibility problems and registry issues, it is really a waste of time to do ANYTHING on ME. My first choice for a gaming OS would have to be WinXP Pro, (is there even any difference between Home Edition?) I have not once had a problem with playing games released in the last two years; in fact, I have never had a problem playing ANY game on XP. Either I am just lucky, or XP is a great OS for the gaming world. For more aged games, I would have to agree with the majority and say that 98SE would be your best bet.
