Back in alpha versions, before command stations and guard posts existed, starships were absolutely crucial and central to the game. They were also called command ships. All your ships were attached to a starship via munitions-boosting-like lines that could stretch as far as you wanted on a planetary map. There were no wormholes, so when the starship warped between planets (which would take about 30 seconds per inch on the screen, more or less, and the line of warp couldn't go through black holes or asteroid fields) it would take all its little ships with it. The way to win was by killing all of you opponent's starships before they killed all of yours.
Early versions of the game were completely pvp for testing versions, and then when I started adding the AI it was neat to watch it retreat, etc, with its starships. But at the same time, it was not any more interesting than pvp, which was already getting stale and repetitive with the game. So that's when I rejiggered the whole thing and turned the idea of what I wanted to do with the AI on its head. The result was that starships became pretty unimportant, and only the AI retained the ability to warp ships (and this from outside the planet, not into), and warp sensors became a lot less useful, and these icons remained somewhat useful (and so stayed in the game), but not so central as they once had been.
Yeah, this game has evolved a long way...
