I enjoyed it. I let her shoot me -- as horrible a thing as it was, she needed to be prepared to do what she'd need to in order to survive the long road ahead.
My main issue was lack of variance in playthroughs beyond context. I've worked in games as a game writer -- I can tell you right now that there were many cheap and effective means of providing a more branching narrative. Carley/Doug could have survived instead of Ben (in fact, even if that had been the only way it played out, it would still be better. It would color the relationship between Carley/Doug and Lee far moreso than it does with Ben). Katjaa should have possibly survived instead of Kenny. They should have included Mark and the military base as the second episode, and just had six episodes (I still have suspicions that this may have been the original plan). It also would have been better to not ham-fist the antagonist in during the last two episodes. Deus Ex Machina moments are getting more common place in games (Deus Ex and Mass Effect both have fallen on this crutch), but it practically breaks logic with TWD. There's just too much "just because" used to explain the narrative.
I could go on, but I'm not going to waste your time with a rant. I loved TWD, and plan on getting Season 2, but... I really think they dropped the ball in some places. It's not my 2012 GOTY, as a result. That award, for me at least, went to Tiny & Big: Grandpa's Leftovers.
I picked shoot, but in hindsight, that was probably really traumatizing for her. At the time, I was just thinking about how horrible it would be for Lee to die alone slowly and painfully, then reanimate as a monster, but that probably was not good for Clementine. I don't think she would want Lee to become a zombie, though.
Out of curiosity, did you side more with Kenny or Lilly?
I played twice just to see all the different reactions - first time, I sided with Kenny most of the time, but I didn't help kill Larry since I knew it could only make things worse. Second time, I tried being a bit nicer to Larry and Lilly just to see if she's less of a bitch if you're nicer to her, and of course I didn't kill him then either.
I do not think you're whining. The Walking Dead universe is similar to ours, but maybe just a tad behind. I do not recall seeing any tablets or smart phones in the televised series and I dropped the comic after like 30 issues because it got hella boring.
