Vudu's claim is no big deal. I could have told you the remaining members of Beta's mafia before the end of the first day. It should also be pointed out that the sides I was on won in their respective universes. The townies in Alpha and the Mafia in Beta. The Khushrenada effect perhaps?
But in all serious, I would say the two most deserving people are Dasmos and Shift Key. There are many moments you could point to as being turning points in the game but they were pretty much the leaders in each world. Of course, it may be that I am rating Shift Key higher because I felt the effect of his game more than anyone else, but he played pretty good. The biggest knock on Shift Key was that he was killed in both worlds and Dasmos lived to the end on Beta.
In the end, my vote goes to Dasmos. I think it was by far the best game I've seen him play and he was the godfather of two worlds. There's no reason to take the victory away from Dasmos today. Shift Key's a great player and will have his day of MVP.
I just wish Dasmos had told me who the mafia of Alpha was. Since I didn't and didn't want to lose my ability to flip to their mafia in the future by being hit, I figured it best to spill all the info I had like DaaMan64 most likely being the killer and my suspicion of Doctor Unclebob as well as claim to be mafia to make myself look guilty. Dasmos knew I could switch mafia's. I even told him of my role and it's ability but he didn't let me know then that he controlled both worlds. I would have changed my strategy completely if I had known. That's my biggest knock on Dasmos. But I think I can get over it.
VOTE DASMOS.
