I don't know, I'm 23 now and while I can still definitely enjoy a good game and even get completely sucked in by one, the quantity of games that I actually enjoy have gotten less.
Right now, I only enjoy Skyrim, Mass Effect, Fallout 3/vegas, pokémon heartgold(I know, I know) and Amnesia for a bit. There's a pattern, obviously, the first four allow you to have a lot of variety when it comes to building your character and have, to a more or lesser extent freedom to where you want to go.
Maybe I've just gotten more picky over time...
