This is the very first released version of Microlite74. It’s only 5 pages long (including the OGL in fine print). It includes variant rules based on Microlite20, a complete spell list and monster list, Microlite74’s rules were written to support the “old school” style, while retaining many of the more modern rules features of OGL games based on the 3.5 SRD. Microlite20 trimmed the fat from the 3.5 SRD, paring the game down to a fast-moving and easy to learn two-page system. Microlite74 takes the M20 system and modifies it for a 1974 style, but leaves most of the basic Microlite20 rules in place.
WARNING: This version is very broken as it was not playtested beyond third or fourth level (and higher level characters are far too powerful for 0e monsters and adventures). The original idea for Microlite74 was that it could be used to introduce 3.x-era players to old school gaming. If they liked old school gaming, I just assumed they would they start a game using “real” rules. So I never actually played beyond third level. When others decided they liked both old school gaming and M74 — and wanted to just play Microlite74 — the problems with higher level characters were immediately apparent, were reported to me, and Microlite74 1.1 was released.
