So really, I would like a rundown of what exactly you people have changed here. I've gone to those other threads and they are teasers, not a bad policy in my book but not enough to justify me spending my whole month's salary (yep, living in a third-world country means I get that few for a payment) in a complete set of books!
Character LawCampaign Law material was removed to be placed into its own book later this year.
Arms LawAttack Tables -- during this process, we discovered that many tables often had minor changes made to them between each and every printing (and not always the same tables). We selected one printing and went with it, so the attack tables MAY be different than in your existing copy.
Tactical/Initiative System replaced - Instead of the multi-phase system from RM2, there is now a single system that uses activity percentages to determine things (when coupled with a simplified init roll -- 2d10 + mods -- this makes faster characters go first, and the mods are based on d100 scale, so that the 2d10 reflects a bit of luck, but it is not overwhelming).
Spell LawSpell Types reworked, getting rid of Passive and adding Phantasm/Illusions as a type. Most of the spells that were Passive became either Informational or Utility. Better guidelines/rules were given for resolving Informational spells.
One spell list (Symbolic Ways) had its spells reworked slightly because of order/power level issues.
Other than that, text was cleaned up and/or expanded to make the intention of the rules clearer overall. A lot of options were added to increase compatibility between RMC and RMFRP.
But that is basically it.....
The original intent was to clean things up and expand the text. However, when we hit Arms Law - that phased system was just too horrendous to be allowed to live on, and the decision was made to euthanize it, for its own good....
The same with spell types, there was a lot of confusion because of Passive spells, the intent was to reduce confusion overall by expanding upon intent....
