I think I just spent more time in Windows than the last 2 years together. GTA IV is fun, easy as that.
I don’t know why people keep nagging at the game, it’s great and just what I’d expect of a new title of the franchise.
The only thing I can really get mad about are the horrible DRM-esque copy protection, the need to register at least 2 accounts (1x Rockstar Social, 1x Windows Live) and the massive memory leak that brings down the performance after a few hours of play.
So, come on Rockstar… Instead of spending thousands and thousands of dollars to keep the game copy-protected, spend a few thousands on debugging the PC version – for Pete’s sake. It really isn’t funny and the fact that the game doesn’t even start with ATi graphic cards is… ok, that’s to be expected 😉 .
