I dunno, 20 years ago Role Master already had nicknames like Roll Monster and Rule Monster...
ive heard all these before, normally by people who never played it, or where biased towards TSR products!
in my own personal experience after converting several TSR types to either Rolemaster/MERP, the general consensus was RM was much more enjoyable! tho i will add a lot of these opinions/circumstances derive from bad GMing! certainly, any rule set can offer players a bad experience! i have played both and have enjoyed both on the same hand i have also not enjoyed both, that being said personally i think RM rocks - awesome system, a damage chart for each weapon!, fumbles, war rules it had everything!
