how do i play GTA3 on windows XP ?

What do you mean?? A friend of mine plays it just fine...but I don't have any real expereience with it

You really need to be more specific. What kind of problem are you having? Will it not install?? Does it crash, or what does it do/not do?
Either way, I am moving this to Open All Topics, as this is not security-related.
