So I have an idea for a fun survival realm with a game aspect to it (sort of):
Would get however many people we wanted (max 10 at a time, due to realm restrictions)
No coords allowed, but OP would give everyone a starter kit, which would include a bed. OP would then TP each player to a randomly generated set of coordinates. Once all players were TP'd, all would setup their beds and sleep to set their spawns.
OP would then change the world spawn to an incredibly remote area, far far away.
Then the "game" would begin. Players could choose to build their base near their new individual spawn point, or set off to explore and find other players to join together.
So you'd know there were others out there, and could chat in-game, but wouldn't know where each other were.
Anyone interested, or have additional tweaks to make it more fun?
