Huh, I had no idea that was the case. How does what3words make money exactly? I assume ads but I block those everywhere I use a screen.

Are there any services that do roughly the same thing but are open source?

The what3words app is awesome and lets you share any 10-foot square on the planet and save them into lists.

I came here to say exactly this. My favorite games for 5+ players are Codenames and Sushi Go Party Edition.

I was just watching a couple friends of mine stream Remnant 2 earlier and it does look pretty slick. It seems there is at least one puzzle that requires co-op to fully solve, and there may be more further in just so you and others are aware.
