try it on hard and see if the pain-in-the-assedness is increased, or is somehow made better...
The problem isnt that it's too easy. It's kind of hard, but I just don't really... care. It doesnt seem fun. I usually clear one or two areas, save, then quit.
It's uber predictable in that 'ok I'll grab the item and monsters are going to swarm me from all over' kind of way. It isnt that I dislike FPS games, because I really like them. It's just this game seems to be missing some intangible something
