I bought the game when it was still considered new after it went on sale at GoGamer.com.

I was looking for another Oblivion style game.

At the time, it was atrociously flawed. Buggy to the point that when it actually didn't crash, it would have dozens of (often hilarious) bugs that just ruined any immersion.
Beyond that, it just felt quite generic. Maybe I wouldn't feel that way had I played the other games in the series when they were new, but having not, it just was not exciting.

Too many others great western RPGs out there now that keep from wanting to retry it.

Speaking of, isn't Risen supposed to be the spiritual successor of the Gothic games? Might want to try that as well. That can be had fairly cheaply now.
