If you like RPGs, look at the 3DS. Etrian Odyssey, SMT Soul Hackers, Devil Survivor and SMTIV, Fire Emblem, Pokemon, Kingdom Hearts, Tales of the Abyss, plus the crazy number of DS titles available at this point. Don't limit yourself to one console/company. Enjoy what other ones have to offer.
PSN: JVir NNID: Jayvir These days, all the kids are playing M rated games while the adults are lining up for Pokemon. Which game is a kid's game now?
What I buys in regards to the Vita is get a game that I can't possibly get tired of, that way I'll always have something to go back to. Specifically I imported Mahjong Fight Club, so it replaced my iPod as my console of choice to play mahjong (real mahjong, not that **** your Mom plays where you clear away tiles by finding doubles).
It guarantees I'll always play my Vita while waiting for releases I actually want to buy. And there's always the possibility of buying more consoles.
Get another gaming device. Don't limit yourself to one.
Get an Ipad.
He clearly doesn't want to/can't play swipe games, which the iPad is full of, so that's not a good recommendation.
Plus, for me and other people I know, the iPad has a lot of games that just feel cheap. You can tell the environments and interactivity are limited by the device more than dedicated handhelds. Plus the battery life always runs out super fast when playing more power-demanding games, and games crash often. Also, the multiplayer aspects are generally not good.
There's some pretty fun games on there, but not really anything I'd put tons of hours into, and I certainly wouldn't use it as a complementary system. The games just don't do it for me. It's good for five to twenty minutes here and there, or maybe an hour-long flight at most (though that's a stretch), but I find it doesn't make for good lengthy sessions of gaming. I enjoy playing my handhelds for a few hours at a time sometimes.
