So having played all five characters, here are my thoughts on them. Be warned, there could be potential spoilers. Now, I'm discussing these in the order in which I played. I know it's technically not going to be the correct order.
Russell: So far I think Russell's an alright character. Nate was an absolute psychopath who seemed to have more than one screw loose. I wonder if he was always like that or if the zombie apocalypse made him that way. One thing I didn't like was how Russell, after telling off Nate at the diner, just leaves him alone with the wounded old man and woman. Seriously kid? You're going to leave THAT guy, a guy who delighted at the thought of killing a helpless old couple alone with them? I thought that was incredibly stupid on his part.
Bonnie: When I first played Bonnie's story, I thought Leland was Herschel (They kind of look and sound alike). The bit at the beginning with Bonnie and Leland discussing whether they'd rather have lobster claws or a snake for a tongue was pretty funny. Not any really bad with this part except by the end, I felt pretty bad for Leland's wife, Dee. I played Bonnie's story again to see if there was a way that I didn't have to kill Dee but sadly there wasn't. One last note of interest but I remember Bonnie mentioning that she was a drug addict who Leland and Dee found. In that case, what did they do before the zombie apocalypse? If they "found" her, might that mean they worked at a clinic?
Shel: My favorite of the five stories. It was neat getting to see the cancer survivors from Savannah again and we also find out what happened to Vernon after the events of the fifth episode. In addition to the cancer survivors and Shel, we also meet Shel's friend Stephanie, her little sister Becca, and Roman who used to go bowling with his cousin Niko. Actually, this Roman used to be in a band(nothing much else is revealed about him past that). So far, this was the only story that actually made me feel sad. The other stories, while they were well told, just didn't have as much emotion behind it as this one did. The choices in this story were by far the hardest to make.
Vince: His story is my second favorite. Keep your eye out at the beginning of his story for a certain someone's family's drug store. Vince's story is perhaps for the most part, the most uneventful seeing as how it takes place primarily on a prison bus but it was still pretty good. Not really much to say about it.
Wyatt: Now, is it just me or does Wyatt look exactly like The Amazing Atheist? Same hair, same beard. If I never heard his name, I would've assumed they made a character based off him. Anyway, his story is my least favorite. It's not bad just...not as good as the others. Basically, Wyatt and his buddy Eddie are on the run from some guy(revealed to be Nate from Russell's story), they hit someone and then, through a game of rock-paper-scissors, either Wyatt or Eddie goes to investigate whether it was a walker or a human. Again, not much to say.
In all, I thought it was a very enjoyable add on. Got me hyped up for season two. I have to wonder what this place is that Tavia mentioned at the end. I'm certain there's more to this mystery place than she's letting on. After all, if there's anything I learned from The Walking Dead game and comic, it's that if something's too good to be true in that universe, it usually is.
