This is a very common and simple RP on forums though I'll explain it if you haven't heard of it:
- the whole point is to become KOTH/QOTH or king/queen of the hill
- you don't need to create characters or anything (though you can if you want) your only purpose is to claim the hill
- anything goes, be a god if you want
- it's fun to form alliances with other people
I'll start:
I claim the hill and build a giant castle from which to rule the kingdom.
