So this is highly hypothetical but as a PSP owner I am a little sad that there are practically no good adventure games in the PSN store. I still have an old Tapwave Zodiac at home and sometimes I'll leave my PSP at home just so I can play ScummVM on the Zodiac.
I know TTG is currently spread too thin to also produce a PSP version of the TTT, but from time to time rumors of a PS3 version come up.
And pretty please, should that version ever appear, have pity with us poor PSP owners who would love to play the games via RemotePlay as well.
You just have to enable it, the PS3 does the rest.
