Is this a dream? Am I lying in a coma somewhere imagining this is the trailer to a game I fantasised about throughout my childhood?
No! It's Starship Corporation, a game where the design of big spaceships (and "planetary installations") isn't just something tacked on, it's what the entire game is about.
Players are tasked with designing the floorplans and systems of a ship, then testing it out under a variety of combat and non-combat situations, before finally being able to sell and buy creations to help fund your, well, Starship Corporation.
You can check out a long, and very informative trailer above, and check out more on the game below.
