I will update this review as the game progresses.

As of 21w24a: TLDR - SEvo, while limited in its scope, does almost everything right! Great building game so far and I look forward to future updates.

You have the unlimited ability to build anything, or fly anywhere in the galaxy, that you want.
The UI is pretty basic and while not the prettiest or best UI ever, it gets the basic job done. Looking forward to seeing a better flushed out UI in the future.
The building mechanics are not intuitive to use, but, it doesn't take long to get use to and the variety of shapes and sizes you can make are fantastic. For an early public alpha game the build mechanic feels more in depth then Space Engineers but lacking compared to Avorion but does a good job mixing the two styles. It does everything Space Engineers fails at. I do hope more intuitive controls are added at some point in the future.
There is no survival mechanics at this time outside of "Dont fly into the Sun". Bummer to be sure but I value the Dev wanting to prioritize core features and major bugs first instead of pointless add-on's or dlc. *glares at Space Engineers*
Multiplayer, I havent tried it yet but from what I have heard from others is still pretty buggy and very buggy. But, it is a planned feature and will be receiving more updates later in the future, so I look forward to seeing more on that.
Subgrids, omg yes! This game does subgrids right! In SEvo any subgrid just clips through the each other rather then throwing your grid into spaztastic chaos like Space Engineers does allowing you to really clean up a design or make something crazy.

Once again Keen, YOU HAVE FAILED!

Again you lock functional blocks the community has been requesting for years to be vanilla behind a f***ing paywall!!!
Again you have shown that you give two s***'s about your community of both users and Modders!!!

Yes the blocks are nice, yes they are "cheap", that is besides the point. Keen has once again said F*** you community, we dont care about you and will use others hard work without proper credit given.

Here are better, identical or very similar mods if you dont want to waste $4 on this s***...

You know, I was prepared to rip on this DLC again but after catching up on everything and seeing the update notes.
I can actually say I am modestly impressed. This is a proper DLC for this game. It contains nothing that is "Needed" for or improves game play overall and is far better than the first DLC.

This Im ok with supporting!

Once upon a time I couldnt recommend this game enough, I used to try to get my friends and brothers to play and almost got most of them to try it. Now, I tell people to stay the hell away from this game and only touch it if they can get this for free or at the very least on one of the big sale days!
I had high hopes for this game in the beginning, it was easy to play, challenging occasionally and once upon a time had a semi decent multiplayer state.
Now though, after over 5000hrs put into the game the Devs have still not fixed any of the major issues. Opting to rather patch over patches thus every few months undo a patch they made and releasing a game breaking bug back into the game.
Multiplayer still sucks and is very buggy with more than 4 people and this is in a VANILLA Client hosted server...
On top of that even dedicated servers suck unless you Torch the sh!t out of a DS... WTF Keen!!!
There is still no legitimate Survival in the game after 6 years and even with the half a$$'ed block progression, can still be end-gamed within a day!

In regards to the DLC, if it was legitimate decoration blocks, you would not have included blocks that players could interact with beyond basic block physics. The blocks that are interactive should have been added to the vanilla state and not be hidden behind a payware wall! Besides these are all blocks that we have been pleading for since near the beginning!
Bad move Keen, STOP following EA steps!

This game should not be out of early access as it stands, hell, it should still be in alpha. Released status is for games that has the vast majority of ALL features WORKING!!! Not Game changing / Game Breaking updates!
