Here's my view as a player: I think that it's the creator's decision to create as they choose. However, these decisions may not be without consequence - the largest monthly amount I have ever subscribed on Patreon was to a creator whose game I was enjoying. After three or four months I stopped supporting them because they were constantly jumping around offering different things, almost none of which interested me, and it seemed like they barely touched the game I'd actually chosen to support.
The second-largest monthly amount goes to a creator who works on one game only, and (other than a brief period when I had to reduce my contribution), I've been happily handing over my money for years.
When creators aren't delivering what they promise, it's not unknown that I'll stop following them. Similarly, creators who start work on a game and then (ultimately) abandon it, I will feel cheated. Sometimes, of course, there are reasons, and I can accept that. Other times there's no real reason beyond, "Changed my mind, want to work on something else now" - which is also fine, but leading the punters along is going to earn you [creator] a reputation that isn't ultimately going to help you as a creator. More pertinently, if you're aiming to make money from your pursuits, people will learn not to trust you, and will be unwilling to contribute - or won't stick with you.
In short, if you're making your work public, try to limit it to a few things, and make sure they're all updated often enough that they don't feel abandoned. And be honest about your expected update schedule. If you're hoping people will support you financially, this is even more important. Alternatively, if you're leaping around like a yo-yo unable to decide what you really want to pursue, maybe don't take it public: you're doing no one any favours. Unless you want to be viewed as a yo-yo.
