I think events can fit, you can have role-playing events,
sports, kingdoms who are fighting against each
other in an organized friendly form instead of
just constantly using swords / magic (on UO).
In the antique and in the medieval age they had many
events, just because the emporers/kings were bored.

The minigames were needed because you
can't always change the whole world just
because of some fun idea, then it's better to
make a place dedicated to it and separated from
the main world.
