Overall it greatly expands the number of players though, even for niche games.
Like I found out about Shadow Empire after playing Stellaris a lot and then finding Dominions 6 as another 4X game, and eventually Shadow Empire.
Shadow Empire (and Dominions for that matter) have a much smaller budget than Stellaris, but they are excellent games that I only found out about after enjoying the genre.
Personally I’d love to see more of a living world like Ultima VII, Oblivion and Dwarf Fortress Adventurer mode.
