I only play my PSP in bed while my wife is sleeping. I am sure I look like an idiot while doing it though.

well since most of the RPG's are on there, i usually play them at home.

I can't vote. I'm really 50/50. I play the bigger epic games at home, and I play all the faster games (Tetris, Peggle, etc.) everywhere else I go.

Mostly on the go, but when I get an awesome game that I can't put down (like the Phoenix Wright games), I burn through it at home before I'd have a chance to use it on the go...

I'm with you Soriku. Basically only at home.

at home cus I don't travel at all unless on holidays

and I live ina small town so I don't need to entertain myself on the "subway/underground"

Commuting is usually my prized time of peace when I can philosophize about the world. I can't sacrifice that for some games. Kind of like the shower or the toilet.

Only at home for exactly the same reason Soriku posted.

On the move, which is why I barely ever play them... but FF VII is very tempting, it is so great {and yes I know that it is not a PSP game, but I treat it as one} and clearly better than Red Faction Guerilla...

Mostly at home now. I played it while riding the trains when I lived in Japan.
