The DS has the better library of games, no doubt. Although in my eyes neither handheld really excels in the games department, comparing it to previous Gameboys. However, the hardware the PSP uses is far far superior, allowing for more potential. This potential shows in all the homebrew and emulators available for the system. Which I think justifys its purchise. The system just needs more original titles, because while the system has a library with plenty of great games, alot of them are rehashes and ports. Not cool seeing as you could probably emulate them anyway.
