What we need to see is a LEE that's in control of the group. Have his role akin to Rick from the Walking Dead. Put the tough decisions on Lee, and watch the weight of his choices unfold for the better or worse of the group. Have choices affect the development of LEE's character- seeing a man with a broken past determined to protect the new family he forms through the zombie outbreak, or destroy their chances for survival through poor decision-making.
I don't want to control a character with tough choices, who isn't the leader; I want to have the tough choices as leader, to witness the various ramifications surrounding my group from the choices I made. What made The Walking Dead comics so intruiging to me, was the adversity Rick went through to keep his group alive amidst a zombie epidemic, even though "humanity" turned out to be the biggest threat. Instilling that sense of a being a leader in a savage world, I think, would make The Walking Dead game really shine.
It'd be nice to see Lee take control as leader, instead of having the thought suggested to him by Carly.
Would anyone else like to see an episode where Lee is official LEADER of the group? Being a leader while taking Clem's safety into account, could see him making real painful and biased choices.
