what wrote:Having played both the PS2 and PSP version I would recommend the latter, as the PSP's visuals are much crisper and cleaner (kind of important for a game which places such a high priority on examining details in the environment), and there are noticeable graphical glitches present in the PS2 version I did not see on PSP.
Interesting... I actually found the opposite to be true. I guess the reason it's "crisper" on PSP is due to technological limitations. I never had an issue with graphical glitches with the PS2 version; I guess I just got lucky.
