PSP DOES have good games, and games that you can't get on the DS, hence why it's a viable system, and please can we stop the "PSP is poor as a handheld" garbage.
THere are a number of peoplehere who WANT the PSP to be dead, because of blind company preference and are saying the PSP isn't a good system (untrue) or that it's dead just because NSMB came out (when PSP sales didn't take a hit with the release of NSMB, that sort of thing is unlikely).
