I have somewhere north of two thousand hours into this game and still enjoy playing. Unbelievably responsive dev team. Mods are fully and enthusiastically supported, complete with an integrated mod portal. The modding community produces more content than anyone can keep up with, so there's guaranteed to be something you'll enjoy even if you get bored of vanilla after 'only' a few hundred hours. The game itself is rigorously optimized to run flawlessly even on ancient hardware, or to scale to ridiculously huge bases on the latest and greatest. Online multiplayer supports up to several hundred people at once. I've played since version 0.15, and the game was release quality even then. They spent three more years putting a fine polish on every aspect of the game from interface to graphics to sound to usability features, plus some additional game mechanics. This game's interface will forever spoil you on other logistics games.
