Hmmm if somebody made an entire episode? Yea I could consider 10 dollars for sure. 15 if it gets some more custom QC support like new monsters and weapon or features that go beyond the usual vanilla stuff. But I don't expect to make a living from that since in game dev you need large numbers. I think you could cover your coffee costs though hehe.
If there was a constant flow of epic quake 1 and 2 episodes on a monthly bases... oh lovely thought 

After re-reading the thread I think I have definitely changed my perspective a little bit. Sock did state he'd release for free after the project is finished, the model would be similar to a patreon model? You pay into the project and that's to support the artist?

I do think I'd pay for an ITS game actually, a fleshed out game would be worthy of my money and time thinking about it. 

If you could make a game scarier than kleshik(and bloodier) then i will pay $60.
Or ₹800(rupees) 

You can count on me. 

Regardless of how good or bad the maps are: When the mapping part begins to make money, the makers of the tools you're using for that can run into motivation problems if they don't get a share. That is even after reviewing the licenses of those for whether such a commercial use* is allowed in the first place - the next version might not be for free anymore. Or the next version might not be released anymore because the billing troubles are a nuisance. The tools are there and ready for use, but they were not easy to make either.

*And it _is_ a commercial use. Worst, even the game studios might not want to see a commercial ecosystem based on their stuff. 

The same set of issues arise when you look at the libraries the tools use to do their work - Not all are necessarily free and open source and maintained by really charitable people. And free or cheap webhosting among friends often comes with rules or expectations regarding being noncommercial.

When you cross borders, issues can get worse - In Germany, for instance, lawful crowdfunding and micropayments put such a burden on the beneficiary regarding taxes, receipts and documentation that it's usually not worth the effort at all, so doing it wrong in terms of taxes (and social insurance and health insurance, at great personal risk) or shunning commercial uses altogether are often seen as more viable options. 

In Germany, going commercial also means adding an "impressum" to your website and revealing your identity.
And it makes you eligible for being sued for patent and trademark infringement, even if you invented it all on your own and had no idea and only generate a tiny sum of money with it. These implications are a little worse for programs than for maps. Suddenly you can need legal counsel that puts your whole finances at stake.

All these issues are veiled very easily if you just look at the simple need for earning a reward for your time and crowdsourcing platforms offer great tools to do that easily... while covering their own asses on the legal side very well.

OK, hope that was my last post part now.
And again, this is no statement about the quality of your work. 

What about patreon? this sound like you need more support for other projects also. Patreon is way to go really. 

At least check out website, there is a lot of creative people. The most important thing is to get founders, and be loyal to them. In patreon you can list out many other things that might come to you mind, not just singleplayer maps, but also list out other things - so people will understand the bigger vision you have in mind.
