Just counted, I have 51 RPG's so far, though some may argue that not all are true RPG's like the Ys games or any of the Diablo clones. There's stil more I'm eyeballing. It's only within the last year I'd guess, I started to find out about alot of great PSP games that I missed out on over the years. I blaim it partially on Wyrdwad(the dude at Xseed that posts over at the Ancient Land of Ys boards), as he sings the highest of praises of the PSP. Though, I myself can't get into the Hatsune Miku stuff & the like. I do have a bunch of imports like the Parodius, Salamander, Twin Bee, & Star Soldier collections, as well as a few stuff only released in english...but only in europe, like Breath of Fire 3 & Silverfall(though, now that I have Silverfall, the gameplay feels real sluggish).
I have played Sword of Mana, but I've never played the game it was based on. I'll have to play thru that one, one of these days. I'll maybe try the Legends again.
