Lieber Frosch als Faschist!
Ich sollte mir mal wieder bei Gelegenheit den Film anschauen.

Yeah, Monster Hunter Freedom Unite was probably also the game I spent most time on my PSP.

It depends on what games you like, but I loved Persona 3 Portable and Kingdom Hearts Birth by Sleep.
If you liked Monster Hunter, you could also try God Eater. It is a really gold Monster Hunter Like with a good story!
