3.5 got out of hand. 4 I ran a game for nine months and everyone wanted to quit. The concensus was that everyone's character was basically the same with different color and the encounter system was to video gamey. 5/next played a few games but the complete lack if character building everyone walked away. I mean when you don't even get feats when you level up and have everything for your class already picked for you...blah. pathfinder started out good, and I like the kit-like system they are using, I am just afraid it may be hitting crazy levels soon. It is still the "D&D" system of choice for my group for now.
