infested, stop being a /v/tard.
No big deal if he prefers JRPGs to WRPGs.
They're both vastly different games with vastly different play styles. Who are you to choose what he should play?
And yes, I have played (and finished) BG2, NWN, Planescape (I bet you'll be harping about this one next). I also finished FFXII recently. Zomg.
With that faggotry aside...

IMO, the DS will have a bigger and better game library in the future, and I think FFXII Agito something will be released for the DS as well.

Honestly, the PSP doesn't have that many games, and if you don't care for better graphics / media centre capability / emulation, and just want to play new games, get a DS.

If you want emulation/portable media centre, get a PSP.
