So go sue Microsoft for doing this for YEARS.. Don't have Windows XP? Have Windows 98? Sorry, that's not supported anymore but it still has bugs. People are still using it. So why don't Microsoft support it? Because they have moved on. They have a life-cycle for their products and once a program ends in their life-cycle, tough. There have been only a few exceptions: Windows NT 4.0 would be a good one. I would say that Civ3 has met Firaxis' end of life-cycle.
Microsoft is FAMOUS for doing this. Using Exchange 2000 and if there is a feature in Exchange 2003 you want for 2000, too bad. Go and upgrade (and pay through the ass for licensing) to 2003 to use it. Microsoft WILL NOT accomodate your request. Where are the class-action lawsuits? No. Businesses just accept and upgrade if really necessary.
Sure, C3C still had "some" minor bugs but it is a 99.9% complete product. Before the imminent release of Civ4, the people that frequented this forum were mostly happy with Civ3.
This thread is largely irrelevant. Creating a class-action lawsuit to sue Take2/Firaxis because Civ4 caused distress or whatever because it wouldn't work on said computer is a joke. The product can be returned for exchange or money-back. The product can be retained for support or a patch from the developer which may fix the problem affecting you. I am sure in the future, Firaxis will be able to fix 95-99% of the true bugs affecting people - this of course does not include those people where their machine is actually at fault but believe it is the "crappy" programming of the developer.
Firaxis or Take2 did not FORCE you to buy Civ4 (Note: Microsoft does in a way force you to upgrade your copy of Windows for that new feature such as further integrated security or further security patching, or coming HDTV support in Vista etc etc etc) so if you dont like it, return it. Sell it to someone else. Whatever. Accept the pitfalls of PC gaming as no game is ever perfect. If those people cannot accept it, I would advise buying a console. However, I am sure that is going to change when Microsoft release their XBOX360. Buggy program? No problem. Fire up XBOX-Live and download a patch....
