Personally I'm quite traditional. I like to pay for full games so patreon isn't truly for me.
While I'm not the main topic of the thread I would like to share my input:
-First of all the main problem that I usually have with creators is that they don't share their "vision" of the game, what do you want to accomplish, what do you want to add... this generates many problems later on.
For example take the NTR fetish, there have been a few games that have added it midway and then it generates quite a conflict. However if you from the start said "hey, this is going to be added" then people would know what they are supporting.
I truly think that every creator should try to explain the concept of the game and what themes will it touch.
-Second we have the problem of who is making the game, what I mean with this is that sometimes the creators give too much power to their patrons and the game ends up shifting from the creator's concept. It shouldn't be a bad thing in itself but the problem is that the creator doesn't feel the same, at first he wanted to do "x" but he ended up doing "y".
-Third we have the problem of trust. Don't take me wrong, I believe that most creators deserve to be trusted, but trust is something that has to be earned because of the moneygrabber ones that exploit patreon and give nothing.
-Fourth we have the problem of time and money, most developers don't know how to be efficient at neither, very few follow the division in projects and each projects divided on tasks, even less can they do a good estimation of the money they will need to pay for x or y thing.
This kind of affects the topic of trust too, because failing to do a proper job at these concepts will have a bad effect on the creator's success or failure.
-Fifth we have the comparisons, some creator's seem to work harder while others seem more lax, but patrons evaluate that from an outsider's point of view, perhaps the game that delivered less content was worked much more than the other that gave more, but because of many factors it is like that.
For example a linear project against a multiple-choice project. A linear one because it doesn't need to take into account anything can progress faster than the multiple-choice ones.
So just to give a tiny summary, the main problems that patreon creators have are:
-Concept explanation
-Concept derivation during development
-Trust
-Time and money management
-Outsider's comparisons.
Not many creator's care about those problems, so I don't feel comfortable supporting them. I just buy games that are ready to be sold because of that, for example bought quest failed in nutaku when it was out and I buy h games on steam too.
Having said that, if we fall under the situation that I find a creator that would cover all those, my support wouldn't be constant, usually patreon games have a really long development period, supporting from beginning to end I find that too much. My limit would be around 50-60$ per game.
