Hello peeps, Recently discovered this sim. Got it a few days ago and I must say I'm blown away by the insane amount of things you can do in the sandbox mode. Building rockets, space planes, rovers, probes, flying in an atmosphere, in space, on other planets, docking, and just blowing sh*t up for fun!...and the list goes on a on. I love challeging sims and this one is prob the most challenging I've ever played. I've been mostly playing flight sims, so I really enjoy the level of detail put into the physics and flight dynamics. Incredible! And it's an Alpha product still! Diddly diddly damn! Pointless post I know, but had to share my excitment.
