Good day everyone. I am presently dming a homebrew campaign that is based off of the d20 style of systems. I want to add an element of larger, epic scale combat with armies to the mix. To that end, I am looking for a simple wargaming system that I can easily adopt as sort of a side-game. The priorities are fun, speed, and simplicity. Realism is not a concern. I usually have 3-6 players present in my games, plus myself. Some of them can be a bit impatient, so anything that requires constant or very in-depth calculations will be difficult. It does not matter whether it is square grid or hex grid, I can find or make maps for either. Thank you very much for any suggestions.
