I used to play at work - but then got a promotion and transferred to new responsibilities. The new IT guy decided to put a sniffer on the network. Ah well. No more work-UO.
BUT
Living in Hawaii is not always that great, time differences suxxor. So there are many instances that I called the office so I could attend an event I organized, or someone else organized. The last time I did that, I actually took a whole week of PTO to organize and operate the Napa Valley Fall Faire... then the Spring Faire 6 months later. These were shard-wide events that lasted several days with multiple guilds hosting different mini events for the populace of the shard.
Damn... good times!
