With the all the new games coming out recently, I've recently been letting new DS and PSP RPG releases pass me by. It's too much to keep up with and I simply don't have the time to play them all. However...my favorite genre, Strategy RPG's, are slowly trickling out in handheld form. Besides the eagerly awaited Disgaea Portable and Final Fantasy Tactics coming out this Fall for the PSP, the little DS has two excellent SRPG's that most people don't even know exist.
Hoshigami: Ruining Blue Earth - Remix was released two weeks ago and is superb. The name "Hoshigami" may strike fear into most SRPG fans, but the original (ridiculous) menu system and crushing difficulty have been fixed (but are still there as options). This game is so much better on a handheld. I've put about 5 hours into this game in the past few days and I'm really impressed. This game has a definite "Tactics Ogre" feel to it. Tactics Ogre: Knights of Lodis and FF Tactics Advance were my two favorite GBA games...so I may be a little biased.
On August 14th, Atlus is releasing Luminous Arc. Another SRPG for the DS. I've got it pre-ordered and paid for. Looking forward to this one too.
