So does that mean supporters get access to the scenario player?
Given the current rate of progress I'd expect 1.0 to be in mid-2027/early 2028.
So I don't think you'll get a ton of support that way.
You'd probably do better having a demo version that limits the character creation options along with positions or similar functionality in the scenario player for public. That way people can actually experience some of what you have to offer.
