i've never played RS Vegas for psp. it should be ok but u know if u've played it on 360 then the graphics for psp are gonna be nowhere up to ur standards. but if u want good psp recomendations then MGS Port Ops is pretty good. I just didnt get into it too much. I've been enjoying liberty city stories and vice city stories. Other than a few lags with traffic while driving fast the graphics are comparable to PS2 IMO. I'd also recommend socom 2
