GTA V - 11/10 (more like 9.5/10. The added 1.5 is personal bias )
Still waiting for the PC version... it's tearing me apart to wait half a year or so for the most successful game in entertainment history. Guess I got to settle with GTA 4 (9.0/10) and Saints Row 3 (8.5/10) until then.
It'll be worth the wait if the controls and visuals are tight on the PC. Just stay away from spoilers.
I haven't been this invested in a GTA game since Vice City.
Harsh words for Black Ops! I found the maps fun and varied. I've never been much of a player outside Team Deathmatch, but I really enjoyed the others. And what four guns are good? I vary between about a dozen for different games.
