I found Saga to be satisfying, didn't render me speechless or anything, but satisfing enough.
My biggest gripe was the battle system and that no matter how long I go around beating the crap out of enemies, I was always short of cash. Rectify those issues and I'll have more than a "hmm this could be interesting" attitude towards Saga II.
Oh and I know this sounds weird, but I want to be confused as hell in the middle of the game and have most of the answers fall into place like they did in Gears. I want mind f*cks in this game.
