I just thought of another possible way to represent large scale battles and other macro situations using ICRPG. The idea isn’t original, and I must attribute it to a different system (Fate). Also, I found only one other thread discussing this, and couldn’t see in it something akin to this beyond representing it as Chunks, but there may be many others my search Fu couldn’t detect, so my apologies if it’s been discussed before.
The pitch is that anything could be a character. That said, a group, battalion, army, or even a country or planet could be represented as a single character, with individual characters (or elements) represented as its Loot items in its own Character Sheet! As an example, maybe you have Rome, with such items as Senate (+2 Wis), Centurions (+1 Con), Spymasters (makes Stealth checks EASY) etc.
