if you want to know what the myst MMO was like, there was a game world called Jalak Dador where you'd drag a friend or two and it was just a big grid with pillars you could click to make them go up or down
the gimmick was the current-day explorers found the world but they couldn't find the rules for the sport, so you just gotta invent your own games to play with it
that's it, they made a game world with no gameplay
make it yourself
