I think we're at a golden age of gaming again. Because of online shops, creative geniuses don't have the burden of marketing and distribution anymore. Just look around on Steam, or Desura. 2D gaming isn't avoided anymore. Platform games like Capsized, Rochard, Intrusion 2, Trine, Dustforce, Mark of the Ninja, and LIMBO are all 2D and are excellent in their own way (though LIMBO is a game on it's own, it's almost.. beyond classic, it's art).
2D adventures are as well rising from their ashes. Wadjet Eye games have a couple of really great adventures, and Hector is as well really worth a try.
And I've spent way too many hours on the Total War series, on Assassin's Creed, Half Life 2.
Err... I eh, maybe I play too many games...
