Grand Theft Auto III (PC Games, 2002)

This may well be the one of the best games made in history. When it was released (October 2001) there was no other game remotely like it, there were many features that no other games ever had, the main one was being able to freely explore a huge map doing pretty much what ever activity you wanted. These activities including driving whatever ever car you could see, attacking anyone you want (sounds bad, I know), and doing many missions which are part of the excellent main story line. So all in all, buying this game is buying a part of gaming history, it doesn't cease to amaze people even to this day. Highly recommended, 5/5.
