I finished the whole thing, all choices, all endings. (SPOILER ALERT.)
It's one of the best games I've ever played. Damn near perfect. I do think it would have been better if Stan had been a black guy, but I know that would have required a lot of changes to the whole second part of the story, seeing as how he works with skinhead bikers and all. But still, it seems like the perfect role for a black man, and the fact that he isn't seems like a wasted opportunity.
Other than that, I just wish that, on the Resistance route, there would have been an ending where Maya decides to Stay with Stan and/or Stan gets the upper hand and takes out Jennifer and John. Because I think Stan and Maya are a super-hot couple, much hotter than Stan and Jennifer, and I would have liked to see more possibilities where Stan and Maya end up together. The idea of Maya willfully betraying Jennifer for Stan in the end is super hot, but no such ending exists. Another wasted opportunity.
So, do you have a sequel in mind? If you choose not to execute Stan in the end on the Resistance route, that should come back to haunt the Turner family in the future, don't you think?
Anyway, thank you. Excellent job. And I look forward to more great things for you in the future! :)
