Until further explanation is forthcoming about how this "explore the whole planet" thing works when you can't fly directly over the surface and land in a spot of your choosing, I'm gonna assume this is pretty much a bigger version of The Outer Worlds with a "seriousness" filter applied over it. Which sounds pretty OK to me, but I also don't think we've got a real contender for displacing Elite, NMS, or SC coming.
Ship combat, at least the small amount of it they showed and talked about, seems like it might be slow, chunky, deliberate, weighty, and subsystems-oriented, which is something I could certainly get into.
I guess they didn't really tell us whether or not there's EVA in space, did they? I'm betting on no, but if I'm wrong, and it's handled well, and connects back to the modularity of your ship and its subsystems (a kind of Space Engineers lite by way of FTL), then OK maybe Starfield is a big deal after all.
Lack of creativity aside I find that I like the chunky rectangular nu-Wolfenstein inspired guns despite myself; suit designs too. I really wish Odyssey had also gone with the more bulky NASA-esque exosuit aesthetics that this game chose. The actual FPS combat looks just as lame as Odyssey: floaty braindead bulletsponges with no reactivity other than a depleting HP bar. Better audio and visual effects, though, and at least Starfield will have a variety of enemies to fight.
Character faces and their animations seem to be carrying the torch of Bethesda's uncanny valley nightmares with distorted out-of-sync facial animations. Granted I'm spoiled, now; after playing Cyberpunk 2077, all RPG facial animations and lip sync look like
Mr. Ed, but what was shown here is particularly bad.
