mmm what else could you pick?
jeanne d'arc is a nice JSRPG by level 5,the art is nice and the premise starts strong tough it devolve into generic JRPG pap near the end
patapon is a pretty original game,it works like a very simplified strategy game but you give order by beating drums in rhythm,there are also small rpg element,the third one should get released recently
if you like card game there is the yu-gi-oh tcg,the last version got released a week ago and basicaly has all the cards released so far,the cpu sometimes pull off dumb moves but it's still pretty fun to play
i made a thread a while ago about zettai hero project which is the last game released by the team that made disgaea,it has the quirky humor and extreme powerleveling we all love in NIS game but as a roguelike it falls a little flat
dungeon maker is a pretty original title,it plays like a crappy version of diablo but the gimmick is that you build the dungeon you are supposed to loot so for example,the game might ask you to get a bone so you have to get enough money to build a graveyard so you can fight skeletons,the action is dull but making the dungeon bigger and bigger is kind of addictive
megaman powerup is a remake of the original megaman,it's done quite well
monster hunter... i loved playing the wii version online but as a single player game played on the psp it doesn't work,if you can get some buddies to play this with you go ahead but i wouldn't recomend doing so otherwise
metal gear ac!d gets a bad reputation for being a "card game" but it's actualy closer to a stealth version of x-com... it's a little slow but nice to play
metal gear portable ops is like metal gear but with small RPG element's added,it's pretty good one
if you haven't played them on the GBA there are all the various sting game,personaly the only one i like is riviera but a lot of people seems to dig them... beats me!
prinny: can i really be the hero is like ghost & goblins but with more awesome wacky japanese humor
kingdom hearts birth by sleep is.... well it's kingdom hearts,i like it but it might not be your cup of tea
