Board Game Arena

I can understand that if you're in person you might play this with 3-4 at times but on BGA? Even with how fast the turns are I don't think it's fun at all to wait for your turn in 3-4p and it adds pretty much nothing to the experience. It's a low interaction game. 2p definitely seems best to me. Whenever I see a 4p game waiting for players to join I'm puzzled. Are players just trying to farm more experience or something?

You are correct in your assessment, 2-player is the best player count, adding more players just adds more downtime. But from a marketing standpoint, many people steer away from strictly 2-player games, so in that way it's appealing to people who prefer a multi-player count. I tried 3-players once and I thought to myself... why?

Just think about : it is greater to won several players than win one only.
And playing with several players affect your strategy: if for ex. one player try fast end the game whereas another - play slower. You should watch both..
