The over abundence of story and cutscenes. Any company that constantly releases games with glitches or it is unfinished when they ship it out to sale. While patching it may make it better when i buy a game I expect it to be finished not a few weeks later.

I hate glitched and incomplete games that need patching post-release (hm-hmm - Fallout).

Easy boss fights.

laggy online
