I can certainly conferm that flight commander has gone down the tubes, because I thought te game sounded interesting and contacted it's author. It turns out that the game was his disertation project for his Msc, and though he finished the disertation, he only got a small part of the game working. As he's now a professiona and married software engineer, he said the chances of him actually doing something constructive with the game are not very high.
It seem to me, that most of the abandoned games in the list just never got finished, perhaps a "Work in progress" section would be helpfull.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
