Damn, it had a really slow start in the first 12 hours, but then I posted on Reddit and suddenly it exploded. Now it has 3.5k views, 850 subscriptions, 43 of 43 positive ratings and is marked as favorite by 30 people. Oh, and I'm on the frontpage of the A3 Steam Workshop. And this is day 3 (or 4?).
So far the majority of feedback I got is very positive, which makes me a happy panda. Also I am glad that I fixed the worst bugs when it still had only < 300 subscriptions... uh.
Should have just said it was Early Access. All the bugs would be forgiven.
I should get back to learning the Arma 3 editor. Only really fooled around with 2's.
