One of the most challenging games that I have ever played, yet it also amongst the most fun. I have played this game for several hours and am currently working on 100% Completion, and plan on continuing to play this game even after that because I don't know if GTA 4 is going to be released for PC. I like playing this game because it is one of those games that allows me to blow off some of the frustrations that I encounter during my day.
