Microlite74 Basic has about 4 pages of actual rules (and about 6 pages of spell and monster lists). It emulates the 0e version of the world’s most popular fantasy roleplaying game in its earliest form: the original 3 little booklets in the 0e boxed set. You have Fighters, Clerics, and Magic-Users, hit dice are all d6s (and is all weapon damage and most monster damage), there are relatively few spells (and they top out at 6th level, 5th level for clerics), and the maximum suggested level is only 12-14. It may sound limited, but it can be a lot of fun. Microlite74 Basic is very similar to the first and second edition of the Microlite74 rules.
