My opinion on the whole thing:
Bringing NPCs to Life: Finally! NPCs act like people instead of stores awkwardly waddling around.
Worldgen Changes and Minibiomes: Sounds fun. Having a friendlier starting area would be pretty neat, and that disc cave looks very interesting.
Armor changes: I feel conflicted about this one. I like how players don't bounce up and down and instead put running into their legs instead of their backs. Sadly, I still think they look a bit stiff. Mayhaps, instead of just extending their torsos or legs to run, they would appear to walk casually at lower speeds, but would slowly go into running, with a lot of spring in their torso and limbs, maybe leaning forwards a bit to be more aerodynamic.
Re-Logic Team News: Glad to see Loki's now officially a part of the team. He's really dedicated and I'm glad he's getting promoted into such awesomeness.
Crimson: Crimson Rabbits? Oh gawd. DAT SMILE.
Auto-Cursor: Looks convinient. I don't see stairs as a common climbing tool, I still make "Nerd Poles" (Thank youuuuu, Yogscast...) and use ropes to get around, so I see this as a building utility only. Still, it'll be nice to not have to pull out my hammer...
Insects: That top guy looks like the same color from a teaser you guys showed off earlier. HMM...
Cultists: A dark and fun boss or mission? Yes please!
Drill Mount: Hey! A vehicle that isn't an animal! Looks fun! I also like the added detail of how tunnels automatically form slopes!
I like it! I just hope the Lunar boss isn't an invasion. God, do I EVER HATE INVASIONS. Well, the wave invasions. Army invasions are fun. The ones that go, like, Wave 1 - Scarecrow, Wave 2 - Scarecrow, Poltergeist.
