Do you play travian? Covert recreation?

Work *HURR!*, what is it good for!? Absolutely nothin'!

We were having a discussion over here about why people play the browser game travian (I wonder if I should link to the game - google would probably like that, but I'm morally disinclined).

At this point someone said people basically play it at work and play against co-workers. I had this reply

So not as a genuine recreational activity, but instead as a way of making rec time at work?

That kind of gets into the 'the only show in town' crowd draw, since there are specific requirements for what games can be fitted in (obviously you can't sit down for a session of fallout at work, for example!). So a game like travian is one of the few that can meet those requirements - thus it's the only show in town (or one of the few shows in town).

It makes me think there should be some new word for recreation at work - covert recreation? Basically games designed around filling the niche of what you can get away with at work AND also recruit your fellow coworkers?
