Community copies are a great practice and all of my other games are free in some way (free, pay-what-you want, or community copies), but I keep Dawn of the Orcs as a paid game. One reason is so I can use it to raise money for good causes by adding it to charity bundles. Dawn will be part of the Typhoon Sinlaku Relief Bundle that goes live tomorrow, with 100% of sales going to typhoon relief for the island of Saipan and Tinian.
I do offer both free download codes and free physical copies to libraries and educational institutes, as well as free copies to reviewers, no matter how big or small your audience is. If you're any of those, please reach out to me at Lymerpg@gmail.com! The same goes if you're a game designer interested in hacking any of my games.
While I'm afraid it's not orc related, I'm particularly proud of my horror game Fear & Panic, which has unlimited community copies.
