It has little to do with laziness and more along the lines of.. Why would I finish this game when I am getting $XXXX per month to not finish the game.
I have been against this model from the start, and I do not think it is a few dishonest/lazy patreons. I would say they are in the majority and that would ruin it for the ones who are honest. Not to go into any specific games, but I feel the pay per month plan is flat out bullshit that encourages the development of a game to find every hurdle and obstacle they can to delay the game being finished in any way shape or form possible. I can at least respect a patreon that is per update, because they need to reach the next goal before they get the pledges.
I truly hope this bubble bursts alot sooner rather than later. All it will take is for one patreon to lose their funding to start the chain reaction that I hope destroys this degenerate model. I am all for paying for a game when it is done, and I spent about $450 on games that I bought for others over the last month. I will not buy a demo of a game. If people wanted word to get out, they would be releasing demos like they do on dlsite before the game is finished. Hell I remember my magazines coming with demo disks, and demo cds as advertising gimmicks back in the day.
I never once paid for a demo of a game and I will not ever do so without getting it as part of a preorder bonus for buying the full game. I think that is the biggest problem I have with this model. Patreon users expect you to buy a demo and it has no bearing on the money used to buy the full game down the road. How much shit do you think Gamestop would get if the $5 put down to reserve a game did not go toward the purchase price of the game? We just want you to pay $5 for the privilege of buying the game from us later on, but it does guarantee your copy of the game! Sheer madness.
