You show me, didn't you...
But thinking about the games I do keep a close eye on or support with my cash, I tend to see different levels of updating. One is more storyline driven, the developer I believe does it full time but has two games he alternates with. Most of those updates gives about say 30 mins of new play if one actually reads the dialog (can't say I always do). The other game is more sandbox, so new content (locations, tasks, & general fun) and bug fixes are the norm. And that's with a full time job, getting married, and travel. Now two other games I supported, one was abandon for health issues and the other got tossed because the person thought they could do better with a fresh start.
So anymore, I'm happy if we get any updates even if its just a bug fix. The list is long with abandon projects with a laundry list of reasons. Just mostly plain old burn-out I like to think, since I suffered the same back in the fan-fic days. Even semi-retired now, I doubt seeing myself spending tens of hours writing or even learning how to create a game even with all the great resources F95 has. But maybe that's for the best, because I have no doubt I would get a ton of complaints about this or that and how I don't listen to this random poster that just popped into the thread about this bug or how I should add more choice in a direction I never envisioned or would. Mostly I'm careful with making demands on other people's time, since I can only guess how many hours does into even what most would consider a "small update". As to games I back with my own money, I think its more a personal choice to what one considers a good investment. One I would keep backing even if the person behind the game went dark for near a year, the other I might keep supporting for a few months before a pause. Those are my choices, other backers can make their own decisions. Don't need some rando trying to swoop in and save me and my money from this terrible, awful, and worst engine ever game.
I will admit, this game is on my list for backing if the money becomes available. I see a lot of creativity and promise in it, even if it may take a year or two to get there.
