Uggh I can't choose!
(Not in any order)
Lee- Was a major badass. I had two playthroughs. On one playthrough he was the guy that stepped up to make all the hard decisions, always putting Clementine above himself. He consoled people, was honest, and tried to do everything morally possible. That Lee was awesome. My other Lee was the bad counterpart. He was quick to attack people and threatened often. He killed many people my other good Lee didn't for the safety of the group.
Clem- Do I even need to explain?
Kenny- He was my bro. A likable but flawed man, I loved that he was nether black or white in morality but gray. Honestly such a cool guy that just wanted to survive and do the best for his family.
Carley- Had a brief flirtationship and I think she offered a lot more to the story than Doug (Who I like too)
Ben- Sometimes he was annoying, and definetly made the wrong call more often that not. But he was so real and just wanted to prove himself. I know he isn't the most popular of characters but I really did like him.
Mark- A very shortlived character that wasn't completely fleshed out, but he was a cool guy that I was very sad to see die in the way that he did.
