(from a 360-centric viewpoint)
Mass Effect 3 ending to an otherwise unparalleled story.
Too many sales for FPS titles / Call of Duty franchise
Too little sales for JRPGs like Tales of Vesperia, Blue Dragon, and Lost Odyssey
Lack of reviewer love for Deadly Premonition (my wife's Game of the Generation. Really)
The decline of the Resident Evil franchise (5-6 were the worst of the series, and I've played most all of them)
General lack of hardcore simulation games overall - X3 was pre-gen for PC, and really unparalelled for sim games
Things I liked:
Rise of F2P gaming and all the free gaming I've done
Indie games - Minecraft, Castle Crashers, and the rest
Smartphone gaming - absolutely loving my $20 Final Fantasy Dimensions
The length of this console generation (some may hate it, but I spent $400 on a console that has lasted me 2005-current. Well, actually, I bought 2, sold one, and got my Xbox 360 for free)
Deadly Premonition
Mass Effect 1
Rise of zombie games
Back from the dead, I'm afraid.
