I'm currently in the process of wrapping up something, though there's still some more time before it'll be released (no date is set yet). After that, I'm going to dig into a project I want to be a lot more open about than I have been for many rescent projects. It's not going to end up as a Knytt Experiment, as the help I'll get isn't what features that will be implemented into the game (I've already decided all of that).
Anyway, I miss the times where my games had these huge credits lists, like in Knytt Stories where tons of people contributed with so much different material. What I have in mind is another game like that, where I can get help from the community and my friends for a lot of the material. However, the problem here is that though I live off game development these days (I need to as I otherwise can't get the time I need to spend creating the games), I simply don't have enough money to compensate everyone involved in the way I'd like to, and it's complicated to write a contract with every party involved and set up money transactions, which includes handling a lot of legal details with different countries and through different payment methods, taxes, and so on. Yet I need to give something in return, something more than just a credit in a list.
So here I'm asking for ideas; how can I set something up, a way I can cooperate with friends and forum members to create a game in the spirit of Knytt Stories, where anyone can contribute, and also get something back for doing so, despite that the full version to the game will be sold (or alternatively, a purchasable big expansion to a free game)?
