Adding the ability to set up a chess board, checkers, ect.... adding some basic games to allow people to well play chess with each other such things. The items can be curos ect....
The ability to carve advanced things.... for decoration ect.... sometimes just the ability to make something helps, not everyone but carving a horse out of wood. Just some advanced crafts could be nice over all.
More reason to interact that are not killing each other. This is kind of important since I am still scared of everyone I meet no matter what clothing they wear. The as I have been remembering people decorated swamps with bodies from newbies they killed, ect.... more peaceful reasons for people to stick around and be a community more then a community of killers.
yes more quests that get people involved that they can pick to do also would help.
