speaking of FF7,
Patapon is a really good game for PSP. there are different 4 beat patterns you must follow in order to advance in the game. for example, O,O,X,O will make your army attack anything it its way. O,[],O,[] will make you run away, /\,/\,[],O will make you defend, etc. There are different classes for your patapons such as archer, spearer, knight, horseman (they have random names ending in -pon, kibapon for example). and they each get different upgrades such as shields, weapons, armor. Ive been playing this game nonstop for a long time now. very fun indeed.
i always wanted DDR on the psp but thought it was impossible. UNTIL.....PSP:Revolution.
www.pspr.us its pretty much a stepmania port for the PSP. runs great just the only problem i see with it is that songs do not load the videos corresponding to them. also it crashes the PSP sometimes depending on your version
