Geist and Killer 7

So this was kind of being spoken about in /v/, and I was just wondering: Can anyone give me the pros and cons of these games? Every time I go into a game store I see them, generally for a fairly low price, but I havent played either. I've heard Killer 7 is good and Geist is kind of alright, but never any reasons why.

I heard Geist is a real letdown. Killer7 is apparently a love hate thing. Doesn't seem like my type of game, tho.

Geist - Not the mindblowing game that it was hyped up to be. But still a VERY good "puzzle"-type game. Think Messiah from Interplay.

Killer 7 - Yeah, it's totally love/hate. But if you give it some time, I promise you'll be richer for it.

Killer 7 has a good story line, good meaning it's interesting and was the only reason I played the game. Cons for killer7 were the graphics and battle system. They were too "chunky" for my tastes and reminded me of the oldschool PSX namco games.

Geist -- wouldn't know. I heard it terrible, so I didn't buy it.
