Here's a high resolution file of the gameboard for Avalon HIll's classic Rise and Fall of the Third Reich. The file is sufficiently high resolution that you can print an extra, extra large copy for mounting on, say, a wall.
Tactical Gamex is an interesting project. In it, the author attempts to update the rules for Avalon Hill's classic PanzerBlitz and Panzer Leader:
Tactical GameX is a new interpretation of the classic Avalon Hill games PanzerBlitz and Panzer Leader. An effort has been taken to bring the play of these games into the 21st Century. Rather than moving all units at a time, players swap impulses, moving an unknown number of units at a time. There are also options to turn the game into a card-driven system complete with random events.
My inspiration for creating this new rules set was the vast (and I do mean vast!) number of supplemental units and maps created by the folks at the Imaginative Strategist. The goal was to create a system that was fully backward compatible with the classic games, but provide a more interactive and suspenseful experience with the option to play with armies from all the nations fielding substantial armies during World War 2.
Gamers of a certain age will fondly remember Magic Realm, Avalon Hill's fantasy adventure game. It is long out of print, but you can find an interesting online game facilitator here.
John Cooper has made some graphical improvements for the classic Avalon Hill game France 1940 and made the maps and counters available as a download. I remember having a lot of fun playing the game, and this artwork is a great visual improvement.
Avalon Hill's classic 1962 Waterloo boardgame has been given a facelift by John Cooper, who makes the redone map and counters available as a free download.
