Oh dear. OK, here you go.
I'll give you a rough overview - not everything we ever tried, only what I ended up with. In my old days, I've come to simplify a lot of things. I stole a lot from the Elric/Stormbringer system (and the unfinished RQ4 draft floating around the net).
Characteristics: Roll 2D6+6 seven times and assign scores to stats as you see fit. (Only works for all-human parties, of course.)
Occupations: Reworked in Elric/SB-style. Each occupation has a list of 10-12 skills and you distribute 250 points among them (more for a higher-powered game).
Skills: Shortened skill list which looks more like the one from Elric/SB. No skill category bonuses.
System: No Fatigue Points (If really needed, I use Fatigue rolls and fatigue levels as in RQ4). All stats except SIZ can be trained to 21 (again, for humans only).
Combat: No separate Attack/Parry skills. No Strike Ranks, straight DEX order instead. Hit Points can go below 0, but you automatically lose 1 hp/rd to bleeding. You die if your negative hp equal your CON.
Magic: Depends a lot on the setting. In my Hyborian campaign, spells aren't simply available to anyone. Cult membership is required for spirit/divine magic; apprenticeship (and minimum INT 16) is required for sorcery. Resistance rolls are POW vs POW (not MP vs MP). Demons (and a few spells) added from Elric/Stormbringer.
That's it in a nutshell. Nothing spectacular, I'm sure lots of groups do similar things. Does that help?
