ARPG - Too Human - this game is criminally underrated. It is easily in the top 5 of all games this gen. Incredibly addictive combat and good loot whoring. If you haven't played, you must try a leveled up berserker for some incredible combat action.
Proper RPG - Mass effect 1 - A little too shootery, but still amazing. Hands down best story for a RPG in this generation.
JRPG - Last Remnant - Another under rated gem. This game is all about the battle system and character development. Story is pretty good for a JRPG, which tend to have pretty awful stories in general.
