Choosing your entire tribe is an interesting twist, I've heard of it but never seen it before. It brings up tough questions. Do you pick 5 of your best friends? If you do, who do you vote out if you lose? Do you pick enough friends for an alliance, and then 2 other random people as boots? But will they even accept to play? And what if they make it to the swap, then you could have less numbers! plus, some people have very cohesive friend groups (out of these 3, I'd definitely say Nick has a very certain group of people) but others will have 2 best friends who don't even know eachother. That will bring a very interesting element as well. If this ends up being a battle of 3 premades, then premerge is definitely going to be the most exciting, although the merge game might be good due to the 3 tribes, there could be a lot of flipping and shit.
