Here So this is just about the most fun I've had playing a computer game in... a long long time. The premise (at the moment) is simple. Design a space craft and launch it. It's quite basic at the moment, apparently there's a planet you can fly to but I can just about hit 30,000 meters at the moment. There are plans to design moon landings and all sorts of exciting things into it. And it's completely free at the moment. Too much awesome, enjoy! Post your height records .
