Without a doubt, one of - if not the best I've ever played - and I've been playing since Ye Olde Days of Pong. Damn work and responsibilities keep getting in the way of good gaming time - but I've managed (a mere) 43 hours of gaming time since I picked it up on its release date, and I've only got 52% of the game finished - quite impressive since games like Halo 3 and COD4 can be finished in 6-7 hours. The worlds created in GTA (well, from III on anyway) offer a perfect way to escape into another place- IV ups the bar here in ways that are just fantastic - and I'm really looking forward to whatever will eventually come out that makes GTA IV look "outdated". I'm sure it will eventually happen, but for now, and for the next countless hours of roaming the streets of Liberty City I'll be happily glued to the 360 soaking in the eye candy and being amazed at Rockstar's accomplishment.
