From what I've seen of their playthrough (and what I tried to represent with this pic), the crew's current playstyle I can summarize as thus...
Ted/Toad: The most likely to run ahead of the others, trying to get a Green Star, Stamp, or the Crown before falling into a bottomless pit.
Lewis/Peach: The most likely to wander around aimlessly, trying to figure out what the heck's going on, before falling into a bottomless pit.
Ryan/Mario: The most likely to play the game legitimately and lead the others before
jumping into a bottomless pit to replenish the lives of the group
falling into a bottomless pit due to poor camera control.
and my favorite, Johnny/Luigi: The most likely to throw everyone else into a bottomless pit...before falling into one himself.
So, roughly speaking, between the Leeroy Jenkins, the Wanderer, the Leader, and the
Manic-Depressive, who do you see as your personal favorite?
NOTE: Any further use of the phrase "Lewis and/or Peach is useful" will no longer be accepted in comments. We hear it often enough from the man himself, I don't need to keep hearing it from everyone else.
Now watch how many people say it anyway, just because I specifically told them not to...
