From now on there should be no reason for those "what world?" threads.
This guide is a simple list of all popular activities and which world they're mostly done in.
The more popular worlds will be bolded for both members and f2p.
Members worlds will be in green.
F2P worlds will be in blue.
If you see that something is wrong or missing please send me a pm.

want to track this so I know worlds for stuff
thanks for guide

Nice thread, it sucks that people cant find this out on their own by less than a minute of reading and trial and error.

would house party world cover gilded alter worlds? or is there seperate worlds for that

I'd say they're the same, I'll edit that in, thanks!

Nicely done.

54 is also a high risk wilderness world

tyvm

Tracked for 3 months.

nice guide but i think you should add the used worlds for example the pvp worlds etc like world 18
