If you can think it, you can build it. If you can build it, you can rebuild it to be better. The only limit to this game is your imagination (and your PC). Right now it is in Alpha and there are a few kinks that the devs are still working on. Some are major, to be fair. However, they are adament about fixing problems and they clearly have a game plan that they are working with. I'll be honest, I've been frustrated at times with the lack of optimisation at the current build, which does affect playability, as it very clearly says that it will in the Early Access banner above. This doesn't mean that it's a game to be passed up though, to say the very least. The game is in development, and the devs show no signs of slowing down or halting progress on their game.
The developer involvement in the community is top notch, absolutely excellent. As many other reviewers have stated, Keen Software House is definitely setting the bar for how Early Access games on Steam should be done. Just the other day I posted a bug on their forums, and one of the devs by the name of "Phand" got back to me in 10 minutes. He had me send him my world that I experienced the bug in and forwarded the situation along the appropriate channels. Even if it isn't fixed in this next update, I'm not going to be here complaining because I know it will be as soon as they figure it out.
But, the devs not only communicate well with the community, they also expand on ideas and are working to make the game better than anyone could have imagined it being six months ago when I first got the game. It has absolutely evolved past what it was at that point and is well worth the asking price. I have bought several copies of this game for friends and have met many excellent builders in the game.
The UI is a little invasive at times, especially when building something from the inside. But, there are mods for that and I have little doubt that it's not something that the developer has on the to-do list. Speaking of which, if you want something that isn't in the game, you can almost always find a mod for it. The modding community is very talented and there are many coding experts that have developed tools for the game that are available to you for free.
And, if you yourself are a coder, check out the programmable block! There is literally a block in the game that you can use C# to program scripts into to execute actions for you on your ship/ station. Not your thing? Or don't know how? Not to worry! You can use scripts from the workshop to make your creation come to life before your very eyes!
While the game is no doubt a lot to take in and can be daunting at first glance, the workshop also has examples of ships you can build, and YouTube is littered with in-depth tutorials to get you up to speed. Not to mention the countless guides from the community that explain everything to you in text, if you prefer that to a video.
All in all, it's a dream come true for someone like myself who spent a lot of time as a kid building Lego space ships. I can't wait for the game to progress further, and it's a very safe bet that it will be the best game of its kind.
