Oh yeah, I can definitely see this being used in a TRPG where you're planning out how to manage all your medieval troops on the battlefield. The orchestration feels huge and is helped a lot by the way the song keeps building up into each new section. The swells are seriously great, it feels like it's always heading towards something. The motif usage here works perfectly too!
I'm not a mixing expert or anything and this is very much nitpicking, but I felt like while the instruments were panned around and had great stereo imaging, everything felt very close-up in my headphones and less like they were all on the same stage. I think it's mostly from the drums and horns, but I could be completely wrong. The mix overall is great, as is the rest of this submission!
