Put my DS in storage recently (just because I was moving and packing a lot of stuff), but with all the Black and White 2 buzz I'm pretty sure I'll be getting it out soon. I'm five years younger than OP
I think I'm too old for Pokemon, not in the Pokemon is for kids kind of way but in the it's the same thing I've been doing since Pokemon blue version. They release a game you capture as many as you can and train them and then a couple years later they release a new game with even more Pokemon. I've grown quite tired with the formula, I prefer to play something else.
I'm 22 and I've managed to get 3 of my friends watching the anime and we already play the games together. If I want to play/watch it, then I'm not too old for it.
Edit: I forgot to point out that I actually have more friends that I can trade/battle/discuss with in my 20s than I did when I was a kid. Ironically, the friends I had as a kid were the ones who claimed to be too old for it.
Most anticipated games: Assassin's Creed III, Ni No Kuni, Pokemon Black Version 2, Final Fantasy Dimensions (Android), Lightning Returns: Final Fantasy XIII
