Devs talk a big game to convince people to pledge on patreon, in reality they are unprofessional and lazy. I seriously doubt any of these devs claiming to work on their games full time actually work on their games as much as they claim or act like they do.
I mean just think about it, at the end of the day all these games are just VNs, render some pictures, write some text, and plug it into ren'py. These games aren't really complex, and if you figure an update takes 3 months to come out then that'd be 480 hours of development time if they were working full time. 480 hours to make an update for an update that's not even an 1 hour long? Seems pretty ridiculous to me, I feel like if devs were actually working on their game for 480 hours the updates would be much, much, bigger.. It seems even more ridiculous when you consider lots of those devs claim to be spending their money on other staff members to help take the load off, or fancy expensive rigs to speed up rendering times, that supposed 480 hours spent working on the game for an update that ends up being 30 minutes just doesn't make sense to me.
I feel like the typical development cycle for an update is spend the first 8-10 weeks working on the game sparsely, work on it for an hour here, an hour there, whatever. Then the 3rd month comes up and they spend the next 2-4 weeks cramming everything in which is why Devs are never capable of giving accurate estimates for release dates. It's hard to estimate when an update will finish when you've hardly worked on it and you have to cram everything in at the last second. It's why I'll never pledge to any of these devs, I'm not gonna pay people not to work lol.
