Watched the stream footage linked above, which the following is based on.
Observations are in no particular order:
No super annoying co-pilot. Whatsherame got irritating fast in X:Rebirth.
The main character doesn't have a super irritating voice either.
The heading markers in third person are a useful addition.
The anomalies are a cool feature, potentially hilarious and/or confusing if you fly into one without seeing it.
The UI looks well crafted.
Sectors are a good size and the map is good.
Travel mode is a good feature, makes travelling around much less tedious.
Highways are better than in X:Rebirth.
Not 100% sure about the station scanning, but it looks better than in Rebirth.
Long range scanning is about the same as in Rebirth, but I'm fine with that.
Landing on stations is very similar to Elite:Dangerous. Docking computer speeds things up massively.
(Optional) Newtonian flight model looks fun, otherwise ships handle similar to earlier games.
Ship customisation looks good, although the ability to compare ship modules would be nice apparently you can, but you need to have a module installed first.
Oooooh, looks like flares are a thing. I'm guessing they're anti-missile lockon consumables.
Capital Military ships require a license to purchase, but that's about the same as the reputation requirements in X3:TC. Large transporters don't seem to have as much of a reputation restriction.
Crafting is still a thing.
Space suits use the Newtonion flight model, and have a repair laser like in X3:TC.
Looks like the AI uses the boost feature in dogfights.
Looks like your shields don't constantly recharge during combat like in X3:TC, instead they wait a couple of seconds after taking damage before recharging.
The docking indicator lights are very useful when docking with large, complex stations.
Looks like there are differences between different races ship components. For example a Teladi Mk1 shield seems to have different stats to an Argon Mk1 shield.
Large Teladi ships look massively different to what I'm used to (X3:TC). They resemble giant mushrooms with thrusters. Smaller ones look broadly similar to X3. The Kestral looks about identical to in X3:TC, which I approve of. I like the Kestral.
Paranid ships look broadly similar to what I'm used to (X3:TC), both large and small.
Xenon ships still look like Xenon ships.
I haven't seen many Argon ships, so I can't really comment on those. The Elite design has changed from X3:TC, where it looked like a cross between a Buster and a Nova. From some earlier footage released by Egosoft, the Nova's design has changed a lot. I hear that the Disco still looks like a Disco, which I hope is true.
The addition of tutorials is very nice to have.
I have absolutely no idea what the main plot is like, the guy in true X fashion just flew off and did his own thing.
Overall I'm optimistic, which makes a nice change to my general pessimism regarding the games industry these days.
I give the game 0/10 for lack of Boron. Wait! I see a Boron! 10/10!
I find it amusing how the guy was praising the autopilot for not flying into giant space rocks, then the autopilot flew straight into a giant space rock. Good old auto-pillock.
