Roberts Space Industries is a spacecraft manufacturer within the persistent-world game "Star Citizen" and its companion single-player spaceflight sim, "Squadron 42." RSI is also your portal for information, updates, and purchases of your very own spacecraft with which to trade, plunder, and protect the citizens of Star Citizen.
Star Citizen, still in early development stages, will not require a subscription, but will not be free-to-play either. Roberts says the game will be available for a one-time purchase. And while players will be able to play in the Star Citizen universe for free, there will also be virtual items available for purchase with in-game credits so players can customize their ships and other items.
