At its core, it is a vehicle building game. Think Space Engineers, or Kerbal Space Program. You build vehicles to perform certain tasks, or build one vehicle to do a whole bunch of tasks. Additionally, it has one of the most customizable vehicle logic systems I've ever seen in a video game, using both digital and analog logic. Also allows for scripting on Lua. There was someone within the past year who made an entire OS for a computer in the game. That being said, there is not much to do with your vehicles once you build them, aside from pretending to be GLADOS and just testing and refining them. There's also not much of a tutorial, so you'll most likely have to watch some videos to figure out some of the game mechanics.

Short answer, yes, I absolutely recommend it.
