Patreon backers get more frequent content updates. Steam instead gets emotes, wallpapers, trading cards, and automatic updates. If you back AND buy on Steam, you can get all your patreon benefits on the Steam version as well.
Sorry to hijack this thread for my questions concerning the CoC 2 version on steam. I would like to support this game with a one time payment (aka steam) but for one reason or another it is blocked from the store in my country of residence. Buying a key from some third party site sounds sketchy as f so I'd like to know if there is a way to acquire a copy in another "safer" way.
