I'm all for the guildships and everything for buffs or what have you, but how about small hook point spots to buy mini games with? There are a few gambling mini games (though they don't go into detail) in a few taverns. Prismatic people, the guild I'm with on orien being a role play guild has so far the closest thing to a flying casino as you can get.

The hobgoblin on the deck as the bouncer, the dancing kobold shaman as entertainment, a bar, training dummy for beating your agression out, a con shrine to help your fortitude from all the dirty kobolds you just drank, a bank and mail box as well as an experience shrine so you can learn your lessons better and a device work station for the deviant rogues. Oh, and a guild chest (small) to put your unwanted earnings in.

I'd so drop the con shrine and the chest for a pair of mini games you could play with fellow guildies/friends.

A couple simple games to put out there: dice games(which we do in guild chat from time to time) black jack, billards.
