personally i think the AI is incridible.. it has its " moments" but overall i really think Bethesda does really good job with the AI
Eh, I find that once you get the a sneak level of 40+, you can literally hide 5 steps away from an enemy and not have them see you. I'll kill a bandit in a room and everyone else would rush there, then I would just wait until they aren't "alerted", then kill them one by one.
I got pretty annoyed by it and didn't want to ruin the game for me that now, I just put on heavy armor, took up Two Handed Weapons and just bum rush a room. I actually get killed now if I'm not careful.
Blocking and timing power attacks is a lot more fun, hehe.
Still waiting on the realism mod. Increasing difficulty just seems to increase enemies' health, not your damage/their damage.
