I already have a basic low poly webgl 3D turn based game : BattleSquad
That I could convert to the FIST system D6 for combat and it could be used to run scenarios and as it uses a procedural building system could be used to make (if I added an editor) or generate levels for FIST.
What would FIST players/game master need/want?
Would an Action Point system for movement and actions in a tile based level be an OK overlay for FIST games or get in the way too much?
