Liftoff Inc. is a comedic idle tycoon about a backyard rocket startup with one folding chair and a five-year plan that just says Mars, written in crayon. Rockets are built piece by piece and physically grow on the pad; payload capacity follows simplified real rocketry, from engine thrust and specific impulse to tank mass, fairing size, and delta-v margin, and failed launches cost nothing but produce fireworks. The launch complex grows to three simultaneous pads and a factory row, missions climb a destination ladder from sounding flights to an exo frontier, and a spin-off prestige system converts each company into permanent legacy shares, mission patches, and research certifications.
