So three random worlds (seeds noted)
World 1- Heavily forested, with a mountainous region in the centre, and nearby swamp same seed as the current world so pretty much the same.
World 2, much more mountainous next to an ocean
Word 3, desert, savannah, next to an ocean leading into a forest, quite flat with a village and chasm nearby.
If people could let me know if they would rather start by a mysterious portal or emerging from a vault I will find suitable locations and set the spawn
World 2 looks great! And I think I’d vote for… portal.
