I played Warhammer for over 8 years, since 6th Edition came out. I have over 8000 points of painted Orcs and Goblins, but have grown increasingly disillusioned with the unbalanced armies and list tweaking that goes on. 8th Edition is the final nail in the coffin for me. I want to win by tactics, not by having uber units crush all comers.
Warmaster on the other hand has a great reputation as a game that emphasizes command and is fun. I want to play big battles, not large skirmishes, which is what WHFB often feels like. While doing Google searches of 'Warhammer Alternatives', I came across the Sodemons Website (well worth checking out) and that set things in motion. Sodemons used double the standard Warmaster distances and rules, combined with Warhammer figures. For most people this size is too much. I have a 5' x 9' table and it would still be too much for me. I have settled on a factor of 1.5 times the published distances and created Quick Reference Sheets to reflect that. The result is a very playable game. I hope you enjoy it.
Below is a summary of the main changes.
All distances are multiplied by 1.5
Drive back distances use a D10, with confusion occuring on a 9 or 10. (D10 is approximately 1.5 times a D6)
Warhammer figures are based on 50mm x 100mm bases (4 cavalry figures, 8 large bases, or 10 small bases fit on one 'stand'). Three stands make up a regiment as in regular Warmaster. (Pictures Link).
