To be honest the only time I ever use real time is when I have no intention of fighting and i just want to run, and thats only with low ap characters, consider this, a 6 ap character has a better chance escaping in real time then turn based due to him not being able to outrun the raiders hes fighting or whatever, where as 7 and up ap your better off escaping in turn based mainly due to the ridiculous time out flaw,
seriously in turn based when you hit the grid and your turn ends your out and safe but if you in real time as long as your being shot at the combat timer doesent run out so your constantly in a state of im screwed oh no.
i think real time is fine for towns but at this point a town battle usually doesent last more then 30 seconds, i think turn based is better for wasteland encounters then real time ever could be, there are to many factors that make it broken, like critters that are always able to hit no matter what and dont have to regenerate ap so no matter what if you stop to regenerate a few ap to fire back your going to get swarmed.
