I make no bones about the fact that I love the D&D Rules Cyclopedia. When WotC still sold pdfs, it was my biggest recommendation to people wanting to dive into classic D&D. It was my introduction to D&D, along with a hodgepodge of AD&D 1e supplements. I think what I loved most, as I took my first turns as a Game Master, was that you had this volume that seemed to include everything you needed for what we thought of as a "full campaign". All the weapons lists, all the compiled rules, progression for levels 1-36, and rules to progress to Immortality thereafter were all in this one 300-page book.
As much as I like the easy-entry product like the Rolemaster Express book for Rolemaster Classic, I really think a book that included all of Rolemaster Character Law, Arms Law, and Creatures & Monsters in one book--not the trilogy it is now. Figure out a way to smash down Spell Law to where it will fit. Add in a full Herbs & Poisons list, as that always seems to be a big hit with the players. Don't tell me it can't be done--D&D Rules Cyclopedia effectively compiled 4 boxed sets, plus new material, plus a setting overview, in 304 pages. Pathfinder is over 570 pages. I have to think the above Rolemaster product would be somewhere in the middle of those two, but hardly unfeasible.
Rolemaster's strength is in its charts and tables, and the abbreviated ones in the Express version of the game do not do it justice. I think the Express approach is great for a low-cost introduction to the system, but more and more, I'm growing to appreciate RPGs that give you everything needed in one compiled product.
I'm sure there are other games out here that would benefit from this approach, but Rolemaster is the first to come to mind. Thoughts, or other candidates for this treatment?
