I've been playing Fire Emblem Awakening. I understand these games are supposed to be hard - hence the permadeath - but I am really glad they made a casual mode for this one. I don't think I'd play without it because my OCD is like "Kill all the enemies + get all the sparklies" and if I tried to do that without having any of my characters die, wow. I don't know that I'd ever be able to finish the game, because I would lose patience with those "I've been playing too long and I accidentally forgot to move my character to this spot and I died" moments.
I would love to play some other grid and turn based tactical rpgs... but permadeath is pretty much a game killer for me, because I just lose patience/interest too fast.
I played Bahamut Lagoon (fan translation) years ago, and I think that game would be ideal for a remake on Nintendo 3DS... I'd buy it and play it to death.
