Alrik's xbox blew up, (I assume it took him with it because he has not been online recently)
So its only you left
Seriously, not being able to run and throw grenades, run and shoot rockets(ok that might be challenging in real live), swim, climb small non-threatening picket fences, drop small distances. getting stuck on nothing, foliage (and lampposts) that were indestructible, etc
Oh not to mention grenades that whenever thrown always landed at my feet
