This game is a great sandbox logic game, where you can explore optimizations and even an artistic style with the way you build your factory and components. If you enjoy building chains of development and resource management this is a game you should pick up without question. It is also important to note that the developers will not do a sale, as they have put in tons of work on this and as content and/or patches are added regularly they will only raise the price as the game develops. I picked up it when it was $20, but the $30 price point is still cheap for the amount of fun and hours played. You won't regret your purchase.

If you are on the fence, when 0.17 drops it will have a new user tutorial and I believe the devopers are releasing a better demo with that one, so try the demo and see if you like it.
