Minimum playable requirements:
- All maps:
- Max players: 4vs4.
- Max size of 6x6 (the green squares you can see in Terry).
- At least 2 reinforcement AI hints, one for each team.
- Non-Walled Siege Battle maps:
- Minimum street width: at least 1 orc unit.
- Attacker and defender deployment zones with proper "Guerrilla Exclusion" zones.
- Siege AI system implemented (optional if the map doesn't have walls, but very recomendable).
- Walled Siege Battle maps:
- Minimum street width: at least 1.5 orc unit.
- Attacker and defender deployment zones with proper "Guerrilla Exclusion" zones.
- Siege AI system implemented.
- At least one Victory Point.

Other requirements:
- You (the author) have to send us the original files of the map (the ones needed to open the map with Terry). The reasons for this are:
- Sometimes authors of maps used in the GCCM mod are no longer active in the community or in the game, and we wouldn't be able to fix the bugs of their maps unless we have the original files.
- Sometimes authors recieve bug reports that have no idea how to fix due to inexperience with Terry. We could help them fix the bugs directly, or we could even fix it if the fix it's complex and send them the map with the bugs fixed.
- Sometimes authors lose their original files due to many different causes (like a broken HDD), losing the ability to update their maps to fix bugs or add new stuff. If we have the original files, authors can just ask us and we will send them a backup of their maps.
