Okay. I agree that the combat should be turn based while exploration is in real time, ala the original Fallout.
Even if that was the case, how did your enemies react to gun shots in Fallout 1? They took them like a man/woman/ghoul/mutant! No enemies moved around or used cover.
If they were melee, they bum rushed you to pound on you, and if they were gun toters they shot from a clear position and stayed in place until you were dead or they were dead.
If the argument is 'real time combat should make better use of AI than turn based', then I agree with a previous poster that stated making that level of real time AI integrated into an RPG would be hard to do (and please spare the Beth bashing of 'it is a crappy RPG' unless you've actually played it through yourself and have seen all the dialogue options, etc.)
While I prefer a pure turn-based combat system for Fallout 3, I don't see how this real time system is so inferior as far as the enemy AI is concerned. I will need to see how the game plays and more importantly how my stats affect combat and other actions before passing final judgement.
