It's awesome, designing ships especially are so much fun.

The early access feels good thus far. Constant influx of new contents, no game-breaking bugs that I'm aware of, backed with solid gameplay and mechanics.

Most realistic gun simulator there is
Only unfortunate thing is that the hostiles are only.... sausages...

Yes

Do KSP a favour and don't buy this thing

I've never feel so immersed in a VN before

I played in standalone version, so my steam playtime is waaaay less than it should be.

Pros:
+ The only sim where the feel of flight is there. Especially true for rotary-wing, where in other sims felt like flying on rails.
+ Extensive systems simulation and damage
+ Great graphics, Supports VR
+ Multiplayer

Cons
- Lots of small Bugs, though nothing exactly gamebreaking
- Will break your wallet in both hardware and software :p

Pros:
++ The entirety of Skyrim SE, in VR
+ Massive amounts of mods, most of the mods for Skyrim SE is also compatible with this

Cons:
- Base game does not utilize the VR medium to it's full potential. You need mods for that.
- Base game barely lets you interact with the world in VR. You cannot grab items etc. You need mods for that.
- Sword fight consists of wiggling your collision-less sword repetitively to the enemy.

Overall I'd recommend, since as of writing there's no other open-world VR RPG that is anywhere near in depth and vastness to Skyrim.
