I agree. Any reasonable person would agree VS is successful.

Define successful. Are the devs working on the game full-time?

Yes. It has an active player base that is growing daily.

You asked them to define successful. You asked them a question. I see them answering the question and defining successful.

You are, by definition, 100% wrong.

You asked them to define successful, and they did (implicitly). The fact that you also provided your own arbitrary definition of successful seems largely irrelevant given that you asked them for their own, regardless of whether VS meets yours.

If that's your criteria for success then yes, there are many such games that are successful. Do you seriously think Minecraft is the only voxel game that can support its developers full-time?

I suppose it depends on what you mean by "uses", but it does store the map as voxels, even if it renders via a polygon mesh.

How are these 2 things related? Why do devs need to work on a game full time for it to be successful?
