Well here's a thought, maybe if you're a tiny indie dev team you shouldn't be trying to make an ultra photorealistic next gen graphics game??? It's still mind boggling to me that no matter how many projects go down in flames new devs never seem to realize that overambition is a fucking poison that will kill any project stone dead.
It's not a question of what graphics style you are after as a dev anymore. Engine's like UE5 make it quite easy compared to like a decade ago. Photorealistic, 2D or what ever you can think of, everything needs work. The other side is, there are already thousands of RPG maker games (or name the engine comes to mind) as a dev you are reliant on feedback, and it's arguably harder to get some people to play your game if you choose a graphical look already recycled over and over for many years.
And it's not like only "small dev's or teams abandon games in Early stages. Bigger publisher studios do it all the time, the difference is small devs go more often that not with previews and alike public to found that project, if it isn't a passion project all along. (Even those go public) That being said, there are also often reasons besides being "too big of a project" for the devs not continue development.
The most common reasons I've seen in recent years when, they lost direction and pause to maybe find back to it, they have started as sort of training in development that project blew up and start all over but with better practice standards for better performance/ spaghetti code etc., have another project they prioritize at that moment, or have personal reasons to stop like them/family getting seriously sick, being stuck in a war or people sending them via social media death treats or other ways of hate for some stupid reason, and they quit development in general due to bad mental health.
I mean what ever it is, in the end no one of us is being forced to play games in early development, we choose to do so. If you think you're being constantly disappointed by games being discontinued, use f95's filter prefix to only show completed games.
And who knows, may be another dev gets inspired by an abandoned project and starts to develop the next banger game or an improved version of it.
