It disappoints me to hear/see the direction RM is being take in. Most of my really great early gaming memories are from RM2, then later RMSS.
I play with some newer players pretty regularly and they are absolutely shocked when I introduce them to RM or HARP and follow it up with something along the lines of "don't even bother going to the website" because it will only aggravate you. Which I think is fair after many many many years of revision for a game that was never broken - just misrepresented.
A truncated RM version could have been produced in a matter of months using bits and pieces of existing versions - my preference:
-the armor & Spell Casting/Lists from MERP (up to level 10 fully populated like in MERP)
-the Base Hit Points/Power Points, spell aquisition & stat averaging from RMX
-Critical Charts from MERP/RMX
-the background options, Primary Skills & professional level bonuses from RM2/RMC
-5 professions - fighter, thief, ranger, mentalist, mage
-5 races - the core 4 plus either a half elf or half orc or high man
-6 cultures (rural, 2x urban, sylvan, nomad, hillock
This is all basically cut/paste
The only thing I might have done "differently" is use 1 melee attack chart & 1 missile attack chart - plus the directed spell chart - and have them with the damage caps built in like RMFRP did (I think) and relied on OB mods based on AT on the character sheet to create a little more separation....
I also would have rebalanced the SM & MM tables to actually be based on TN100 or used the HARP table because it is very diverse in what it lets you do.
This could have been to market quickly and been compatible with almost all, if not all, existing material. I would have spent resources on making the books beautiful and developing adventures and actual intellectual property. A system is incredibly hard to protect from piracy (I'm looking at Against the Dark Master).
