Bad interface design
is a real problem, but it didn't bother me too much. I guess I just have more patience than your average gamer. Also, I don't get it why is stealth so bad? Sure, you don't get to hide in shadows, but other than that it's pretty fun. Especially if you don't use Shadow Operative too much.

I think the main point the blog makes is that Obsidian is not that good developer.
