Hey NASA just released their game -- "Moonbase Alpha". I think that's the one that MA had competed for IIRC. Just released July 6. It's free through Steam. And that's not MA's "dynamic" free, it's really free.
But isnt it more an educational program based on real facts than virtual fantazy? To me it looks a little class room boring, but maybe I'm wrong? It's not as if aliens will jump out of the closet or something, is it?? (that might change my mind :D) Old serie was called Moonbase Alpha btw - my dad used to watch that and I loved it! Today I have to laugh when I see it and hear the echo from the studio scenes :D
