GT Mobile is not GT5. Its a portable version of Gran Turismo. I'm sure 100% of GT fans prefer to play on a big TV. But you are missing the whole concept of portable gaming all together and that includes GBA,DS and PSP. And playing GT2 on PSP is a blast on the go.

which game is gt mobile based on...gt1 with better graphics?

It's a seperate game, it's not called GT1 mobile, GT2 mobile of GT3, GT4 or GT5 mobile, it's just GT Mobile. In terms of development, it was started while GT4 was in development, so in that sense it would probably take most of it's cues from GT4. But it isn't GT4 on a UMD, GT4 would never be able to run on the PSP. It's just another GT game.
