First thing I noticed was GTA 3, and remembering the pure amazement I had playing that game, and enjoyed it so much I even drove around the city just for the hell of it.
IMO Ocarina of Time should be in that list as well. But it still seems like a completely well thought out list.
Although everyone will have a different list, overall they got a good list there. I won't bore people with why they didn't include Uncharted Waters, oops seems like I just did .
LOL , no C&C , no Warcraft or Warcaft II and like someone pointed out no AOE, also no DUKE, Descent, Half Life, and a score of RPG's that shaped the modern ones now, also for 2000+ add Stronghold and Heroes of Might and Magic. Oh and i forgot none of the M&M made the cut ... worst list ever.... like the fact that Desktop Tower Defense is there and Angry Birds...
There were some amazing games since 2010 (well.. like 5 or 6 at most that are worthy of the 'classic' title), but they were all sequels to superior games of the past. At least their impact, and advancement of gaming was greater in their own time.
