Unrealistic?! This space game? No way?!
Moreover, technology and technology don't always go together. In the 1970's people assumed that in 30 years we would have a moon base and perhaps a Mars base. Why? Because we just put a man on the moon is why. We had the technology. Obviously in 30 years that technology would make the same progress that, say, air travel had made, no?
And a base? Well, a base requires a self-supporting closed ecosystem. We haven't quite managed to crack that nut yet; the longest try is 15 months (Biosphere 2) which ended prematurely as oxygen dropped, CO2 levels fluctuated wildly, animals and insects died uncontrollably and plant life balance went out of whack. Meanwhile the crew developed psychological problems and, no doubt affected by being cooped up together, oxygen shortage as well as hunger (food production was unreliable) turned on each other in petty squabbles. Turns out you need a lot of different technologies to build a moon base. Getting there is the easy bit.
That's more the will problem mentioned previously. Technology has come a long way, and if someone was motivated to throw some money at things, we could colonize the moon, perhaps even Mars, in short order.
You don't need a closed biosphere for a space base, just semi-regular resupply.
We know way more now than we did at the time of the Biosphere 2 experiment (much of it gleaned from such experiments), and even a carbon copy of Biosphere 2 could have sustained people indefinitely with a few tons of supplies at yearly intervals.
