Previously I would've recommended it, until the developer announced they were dropping the game so soon.
I was a backer since the start, and thus I've seen it grow over updates with ideas that wetted my appetite proper. DoubleFine has released some good games but sadly this one won't live up to its potential.
While it is in a playable and semi-enjoyable state much to their credit, with the devs now giving over the code for the community to develop on, its still a kick in the nuts and the game is left at only a fraction of what they promised Spacebase DF-9 was going to be.
> The AI are smart and respond better than previous versions - especially the Security Teams compared to before.
> Everything works as it should while base construction takes time and effort to complete, pro-longing gameplay.
> A few tid-bits like emotions, items, research and random events, as well as managing happiness levels.
> The only learning curve is starting off your base. From there it is down to experimentation to what you do.
> AI are still dumb at times. I've seen people stand in a corridor when a meteor shower hits the base, or people outside the airlock suffocate because they're waiting in line and their suits run out of oxygen.
> Limited gameplay. Once you've built a self-sustaining base, researched everything and mined every asteroid, thats it. You're done.
> Limited reply value. You get one save file and one base, unless you manually switch them out in folders. Every replay is building the same base again until you come up with an efficient design that always works - its more of a time waster.
> No more official development. You'll recieve support, but any further addons are now in the hands of the community.
If you're looking for a time waster with simple space-base building mechanics, then maybe this is for you. Its quick to load, has enough advanced features to keep things interesting, while you don't have to micro-manage everything.
If you're looking for a game to compare to Space Engineers however? I'd suggest saving that money. You'll likely make one base or two, learn the mechanics, develop a strategy to quickly 'win' everytime and get bored quickly.
