A fantastic game to sink 10's to 100's of hours into, good graphics, intuitive controls, every factory completed pushes you toward 3 more that you have yet to build, designing for aesthetic or efficiency can get tiring over enough time but this is broken up quite well by having 3 handcrafted worlds to go out and explore, enjoyable in single player and even stronger in multiplayer where you can have up to 4 players officially supported but not capped so you can try to add more if you want.
