This show is so damn great. All the small changes they've made from the games completely make sense for adapting the story for TV, but all the big points they're absolutely nailing.
I've also listened to the first two HBO podcasts (hosted by Troy Baker who voiced Joel in the games, and he interviews Druckman and Mazin) which give a lot of interesting insight into just how deliberate and careful everything they've done is, and the rationale for things that are slightly different from the games. Like, the scene at the end of episode 2, having it be infected instead of FEDRA soldiers arose from Mazin asking "why would FEDRA even be patrolling out there in the first place?". It's not a major plot hole in the game of anything, but the tweak for the show makes it a little more logical.
