I bought my GTA3 in release day . Now im playing this since 2005 on MTA everyday. But MTA:GTA3 need some fixes...
Maybe try to find GTA3 on ebay or from rockstar homepage as GTA trylogy(in my country was released pack with GTA1, GTA2 and GTA3 and it was cheap. In my country is still possible to buy GTA3 .
