Please help, wich psp games should i buy?

Im looking forward to an RPG game, ive heard good things about disgaea and others, but theres some other good looking games like metal gear portable ops and logans shadow, oh and castlevania too, wich should i buy, or new suggestions are welcome too, because i wanna buy 2 psp games tommorow, i already have the awsome final fantasy tactics: war of the lions, ultimate ghost n goblins, locoroco, wipeot pure, killzone liberation and some others.

Thanks in advance guys, i dont care if your suggestion is an old game, new or old are the same for me.

I like MHF2 or Radiant Mythology...or just wait for FFVIICC

I have a question about disgaea, the story is serious or is it not? or at least you get into it?great_rulo

Nope, Disgaea's story is not serious. It is funny. The entire game is hilarious - penguins that explode when you throw them, a Demon Prince who overslept and etc. I enjoyed the game, because it is actually quite hard to make a game that makes you laugh and Disgaea did it. The game is charming.

You can check out the game's reviews at Gamespot (Disgaea : Afternoon of Darkness).

Well, I just want to warn you that Castlevania IS CRAZY HARD. So you'll be playing the same stage, maybe 10-20 times before 'mastering' it. The bats fly out of nowhere! >.>superbirdy2

Thanks for the warning but i love difficult side scrolling games, i dont think that the game can be that hard, ive beated super ghost n ghouls for the arcadias, castlevania III, and im a fan of Contra so anyway i really dont care much about the remake i just waanna play the original rondo of blood and Castlevania: symphony of the night for the new dialogs.
