I fear the day when a controller in the rec room breaks, and they realize that the reverse is also true.
Now you just need space for all of them.
I guarantee that for something as fundamental as the main periscope control, _everything_ is going to have replacement parts. That's why $30k is so expensive, it's not $30k, it's $60k or $90k or $120k. Now they have the kind of problem that's fun to have: for half or quarter of the cost of replacing that proprietary controller, they can have so many '360 controllers they won't be able to store all of them on board.
They don't just get to stop at neighborhood grocery stores, after all.
It was hard to imagine living in there for months at a time. One person in my tour group almost started freaking out just in the ten minutes we were inside.
Thanks!
