I was spending some time looking at NASA spacesuits, and I thought that a cool mechanic would be the evolution of spacesuits in career mode. -You would start out with a basic suit like in Mercury missions that wouldn't allow EVA, and you could spend science to unlock others -As you researched those options on the tech tree, you would unlock EVA capability, but with no crew jetpack, like Gemini. -Then, you could unlock specialized suits, like planetary exploration suits to increase the amount of surface samples you could carry, or an escape suit with an included parachute. -And the astronaut complex would become more important, because choosing the crew and the suits they wear could affect how much science you gain on a mission.
