What are some good RPG games for the PSP??

Because I've seen a lot of reviews for most of the RPGs for the PSP and I heard very bad reviews on pretty much all of them...

You think they should work more on RPGs for the PSP??

Tales of Eternia, Popolocrois, Tales of the World, Valkyrie Profile are all RPGs on PSP that I like very much :)
