First time I’m hearing about this, sounds super cool! Is it like Total Annihilation? Because I LOVED that game! I’ll follow this thread, super curious now, hoping someone knows it!
If you're looking for some nostalgic vibes, check out Octopath Traveler for a retro RPG feel with modern mechanics. Also, the collection of Mana games are great if you grew up with the old school JRPGs.
