Moonbase Alpha is my new obsession. Go try it out for free on Steam and get your NASA on. It's pretty addicting but pretty hilarious in the sense that it's trying really hard to be badass and intense. Grab your astronaut buddies and save the day by repairing your Moonbase that has been damaged by a meteor. Though it only boasts this one scenario NASA promises more in the future. What do you have to lose? It's free.
