Blood, Guts and Glory Elizabethan Apocalypse RPG
Blood Guts and Glory is a free RPG with a unique setting: Elizabethan Post Apocalypse:
Blood, Guts & Glory is a mash-up game that takes two specific out-of-print editions of a different games and blends the rules for the two games together, using the best elements of each system. For legal reasons, neither of the the games nor their editions are named anywhere within this site or within Blood, Guts & Glory itself. However, this doesn’t matter. If you know the games then you will pretty much instantly recognise them, and if you don’t know the games then it doesn’t matter – you can play Blood, Guts & Glory on its own merits.
By default, Blood, Guts & Glory is set in and around a post-apocalyptic Elizabethan London. The human race is extinct, and Elizabethan society is now populated by the various animal folk that have inherited the Earth.
However, the game can be played in any fantasy setting with little to no modification of the rules (and such modifications are suggested in the book itself).

Charge Yr Pikes
Charge Yr Pikes is a set of free wargames rules for the English Civil War. The authors write:
This set of rules is considerably modified from the first edition, which was in turn a modified version of CAVALIERS AND ROUNDHEADS’, by Gygax & Perren. These modifications were based on general dissatisfaction with the parts of the first edition that contrasted most with the “Brom Standard” rules which were introduced to our club by Larry Brom. The later editions (3rd, 4th and this one) are merely attempts to “fine-tune” the second edition.
