Some of my own thoughts on the subject:
I think Rolemaster would greatly benefit from getting rid of some of the more cumbersome rules that really throw back new players to the game. How many of you had to read and reread the section on deteremening base hit totals and concussion hits?... and then read it again when someone leveled up?
Also, scaling numbers down makes any game run smoother, and RM has always worked at the top of the dice pool. Now I am not saying the RM should go from percantile to a d20 or anything like that. As an small example: reduced skill costs creates a smaller alotment of DPs, which in turn reduces the amount of math involved, making skill selection easier. The new combat charts in the new Arms Companion reduced the size and cross referencing of what RM generaly uses. This new system has greatly sped up the game without sacrificing what is essentialy RM.
Rolemaster also needs, IMHO, a deeper explanation of the rules and concepts. As it stands now, RMC Character Law, is presented in a way that is relatively clear for veteran gamers, but in the hands of someone new to gaming in general, might find it hard to follow.
Rolemaster is truly one of my favorite games, and I really would like it to succeed. What I don't want is for it to continue it's reputation as an "after market" game for curious or burnt out D&D fans.
Thats all I got for the moment.. I have more to comment on later.
