The Big Book of Games Volume One

This 64-page book contains twelve games and two role-playing aids (though it claims it simply has 14 games). The games range from hex-based combat to a chess variant to abstracts to a party game, a trivia game, a word game, etc.

Most of the games require dice, counters, and other physical components not supplied. Four of the games have maps appearing in an appendix. The first four games listed below tend to be at least medium complexity, while the later games are a bit less complex.

The Table of Contents reads:

Wargames

 Space Fury
 Wizards & Warlords

To the best of my knowledge, there never was a volume two.

EDIT:The 2004 release has 2363 pages and claims to have every Warpspawn game up to that point.
