I sporadically post exclusive discounts to the mailing list, which I did in the past when releasing new asset packs. As an example, only subscribers got "Isle of Lore 2: Hex Tiles Regular" for 25% off on its release! On a later date, I put the asset packs on sale for everyone, too, and as a subscriber you will be the first one to find out! In the future, the exclusive discounts will cover games and software I create, too. Beyond that, I keep you up-to-date on projects I'm working on and cool stuff I discovered as both an indie game enthusiast and as a game developer.
