PSP is lame. Who owns one? I don't know anybody that has a PSP. Yay, 95% of the games are old playstation games and then if you want to watch movies you have to buy it in a new format which is just more wasted money.
$200 for the PSP
+ $ for accessories
+ having to buy all the games/movies over again....
You'd be better off buying a cheap laptop and watching your own dvds or burned videos on it. It might be bigger but it's still portable and can do far more than a PSP can.
Honestly I've been turned off to Sony and Microsoft X-Box ever since computers have been a better value. Which is pretty much when ps2/x-box arrived. They are just glorified computers disguised as consoles. Yet I've remained loyal to Nintendo because they are always coming out with innovative new ways to play games. Dual screen portable system with a touch screen, the nintendo wii with remote, etc. Sony/Microsoft don't have this in terms of gaming. (and no I don't think the little tilt detection in the ps3 controller counts for much)
Call me old fashioned, but I want to feel like I'm playing a videogame when I play a videogame... I don't want to feel like I'm playing a PC game with a gamepad.

But yeah, to stay on topic... the only way Graal would work on a console is if it had online mode. Graal as an offline game is nowhere near comparable to the game it was based off of. It might make a decent minigame for a phone or something though.
