Post-appstore cut it's 42%, which is high but doesn't seem crazy. The unsuccessful attempts and idle piddling all need to be subsidized to allow the successes to exist in the first place, and I suspect we all know better than to undercount cloud, hosting, SRE, and staffing costs. They're all ongoing and pretty painful, and getting a shot at creating something with effectively zero downside risk (vs making a game in Godot and building/buying all of the other parts yourself or with staff) will always come with a lower upside.
