I played Geist on recommendation (from several people, many here) and was underwhelmed. The FPS aspects lacked depth and polish, and the ghost/puzzle aspects, while interesting, could have been played out much, much better.
I'd like to see something similar, but with a stronger focus on the ghost features. Like, maybe a game that was totally ghost oriented, about haunting people or something similar.
The plot was corny, too.
I finished it, but I didn't feel the sense of satisfaction I get from Nintendo games.
(In regards to RE4, which people are comparing it too, RE4 was much better but far too long. I was ready for it to end by the end of the first disc. It was the same exact thing for twenty hours, eventually just became flat out boring)
