GTA2. Cheats. Awesome.

Downhill from there. That's not as bad as it sounds though. Probably the second best game relative to the 3D GTAs is kinda like Brent Knoll to GTAs Everest.

I always though GTA4 was a massive let down. I have completed all the GTAs except that one. It doesn't seem to hook as well as the rest of the series has. Also, I don't know what the stupid tossers were thinking when they made it. "Hmm...ever think we're a little too sandboxy?" "Yeah, let's take out the ridiculous and just make a normal game". Yeah, because that's why I buy GTAs. They're so wonderfully normal.
