Cuz this shit's addicting. FTL is a spaceship / strategy / micromanagement game. You manage your crew, ship, upgrades, weapons, drones, life support, doors, sensors, boarding parties, travel directions, quests, scrap (= money), etc. You fight other ships 1 on 1, in a battle of energy management and tactical targeting. Everything just fits together and allows for many different strategies. An all mantis men crew so you board your opponents to murder them on their own ship? Combining ion cannon with fire beams to disable their shields and set their systems alight? Swarm them with drones? Or gamble everything on a hail of laser fire? You can play only one campaign at a time. You pick a ship, with a certain layout (every ship has two possible layouts, of which one you need to unlock). Campaign usually takes about 45 minutes to an hour to complete, unless you die early. Once you die you have to start all over. On your way through the galaxy sectors you'll run into different events every time. Almost everything is randomized. Random Let's Play explaining mostly everything (he's pretty bad at it):
