MonoGame sounds totally fine to me — as long as I can test builds easily and drop in art, I’m good. A lightweight setup actually fits GAP better than a big engine.
As for the gameplay, here’s the core idea:
GAP is a galaxy‑expansion game where you start with one planet and gradually colonize star systems. It’s not action‑based — it’s more about managing growth, resources, travel times, and expansion routes. The player builds structures, upgrades planets, sends ships to new systems, and expands their influence across the galaxy. The focus is on progression, exploration, and watching your empire spread.
If you need more detail on any part, I can explain it.
And for communication: I don’t use Discord, but I’m fine staying here on itch.io or switching to something simple like email if that works for you.
