Because it's interesting to know if my hypothetical video game similar to this is worth a few beers on a night, a fancy dinner, a year's salary, or enough to set me for life a la Microsoft's purchase of Minecraft. Depending on that information, someone could choose to build a game as a labor of love, build a game as a for-profit venture (haha), or decide to go do something else with their life.

To consider the act of asking rude depends totally on culture and milieu.

What big changes has Microsoft made? The whole Java/Bedrock split seems like a mess, and the updates have been enjoyable, but certainly nothing to write home about.

The only vaguely interesting thing I can point to is Minecraft Dungeons, which was fun for a month for my friend group, and then it wasn't.
