I've followed a couple games like that, and the end result is disappointment. Every feature that didn't work out feels like something I really wanted. So, really, it's a lot of effort on the developer's part to more thoroughly disappoint the potential buyers.
In my outsider's opinion, spending that time focused on building something fun without the outside world intruding would be better. When it gets to the point of only needing polish, then start showing it to the world.
Problem with most popular games is that they are not made by hardcore gamers but by cashgrabbing businessmen and huge companies (you can find out more here https://bit.ly/2ILPdHw). Most indie games, if not 99 percent of them die being unseen. For example fortnite, althrough popular and addictive, it can only addict people new to such mechanisms (to games similar to fortnite) or 8 year old kids who never played. But does it make money? Oh boy.
