All of us gamers by know fairly well know about crowdfunding through Kickstarter and Indiegogo. One we've seen a couple times
before is also Patreon. For those that might not have looked into it before, it's basically a subscription service for a project someone's working on. For a fee (that you decide what level you want to back at), you'll get access to different parts of the project as it goes along. A bit different than Kickstarter and Indiegogo in that there's no, "we need to hit this amount or we get nothing!" type of goals. Instead, when certain funding goals are met, that might allow more rewards as part of the campaign. Anyway, if you're interested, OnePageRules has started up a Patreon campaign.
From the campaign:
OPR is a miniature wargaming project best known for the development of Grimdark Future and Age of Fantasy, our miniature wargames are designed to be fast to learn and easy to play and are released entirely for free. All of our games can be played with any miniatures from any manufacturer or even with your own creations.Source
This project was made by gamers for games and it can only exist thanks to the generous support of our awesome community!
