Past 2 years I am not sure of, as I never know when shit comes out (Unless its beforehand, then I know it till the day I buy it and then i don't care anymore haha)
Those are 3 of the newer ones I know of that I found to be some of the best...
If you want other games, I have other posts in other threads with somewhat large lists of good games, i'll look for 'em real quick...
Haha nice, you'll enjoy some of these, I am sure of it
Black Sigil (As far as I know, nobody really knows about this game, but I really liked it)
Kingdom Hearts 358/2 Days
Rune Factory (pretty much only played 1, but I think the others would be decent too, although Rune Factory isn't for all people, its just a nice little spin off on Harvest moon imo)
Yoshi's Island DS
Disgaea DS (If you have the Ps 2 one, not much of a point in getting it for DS)
Digimon World :Dawn (or Dusk)
Dragon Quest IX: Sentinels of the Starry Skies
Lunar Dragon Song (Not the best, but if its cheap, its worth a play)
Final Fantasy III (Remake ofc)
Nostalgia (I still haven't played through the whole way, but from what I've done, it seems to be worth a mention)
Phantasy Star 0 (Not the best Phantasy Star out there, but if you enjoy that type of play, it may be worth a buy)
of course Pokemon!
Hero's Saga Laevatein Tactics (Once again, still haven't played through the whole way, but fun strategy game)
Lock's Quest (Not played through whole way, but fun strat game)
Not really rpg but: Kirby: Squeek Squad
Ragnarok DS (If its cheap, its worth it)
Children of Mana
The Legend of Zeldas (Phantom Hourglass, Spirit Tracks)
Animal Crossing: Wild World (if you like AC)
Megaman ZX Advent (Megaman X style play i believe)
Mario & Luigi Partners in Time
Holy crap... I forgot about Mario Kart DS, Chrono Trigger, and Super Mario 64 DS(Not sure if its 64 DS or what, but its 64 on DS pretty much haha)
Thats all I can really think of right now, hope you find them fun! If I come up with others, I'll try to edit this post, or make a new one.
