Heh. "TSR" They went away long ago... Regardless, I agree with you on 4th Ed, and I think that is exactly what they were aiming for, to be honest, given the popularity of MMO's. #.5 isn't bad, certainly better than 2nd or 1st (in my opinion, that is), but none of them compare to RMSS for how I like gaming.
Either way, if you change your mind, or your schedule, let me know.
