Basically this game.
http://www.havenandhearth.com/portal/Which I tried to get people from the forum to play as a community building project.
Saz begged to be involved, so I let him.
Premise is, you have to team together and cooperate to build a small iron age village. However, most of the game involves having to deal with various levels of sociopathy and due to the communication barrier its one of the few online games i've seen that actually has ingame xenophobia and racism and such griefing takes a number of weird forms both within and without the community your trying to build (which is quite interesting on a number of levels I think and generally most people agree's is what makes the game intresting).
Anyway, I will admit he started off fairly cleverly, by essentially planting evidence suggesting (as we'd had to move once previously due to this happening for real) that one of the larger Russian clans on it were moving into the area and looking to basically enslave us all (this actually happens quite a lot in the game). Paranoia being the default state of the game, I took him at his word. So we moved.
After that he just resorted to griefing tactics and as a result the project began to fail as people couldn't be f**k to play anymore with someone supposedly on your team just being a massive rooster. So we basically moved again without telling him (which I can imagine he handled with his usual level of self-control) and then managed to set up a fairly successful village that lasted untill the end of that particular instance of the world. We also managed to get Emerald completely hooked on the game and she's now a pretty big deal in it.
Considering as with any game it involved quite a bit of investment of time, it was of course, pretty annoying and i'll admit I called him many things but a child of god. Defining point in anyones life or even in the game, nope not really. A few days later we were happily prospering saz free.
I imagine his account will conflict though.
