If you check the help text that appears when you mouse over the number of systems, it states that doesn't apply to Known Stars games.

I think I’ve requested this before, but would it be worth thinking about the design of the New Game screen some? It could use a few improvements.

For example, the Known Stars option is a big choice that really defines how the rest of the game feels. When enabled, it causes several other options to be ignored. Perhaps this should be a big hint that should inform the design of the screen. Imagine having radio buttons to select between Random Stars and Known Stars. When Random Stars is selected, the options that only apply to Random Stars game are enabled and those for Known Stars are disabled, and visa versa. For easier comprehension, these options should be visually arranged so that the association is obvious at a glance. Or see the attached picture. Of course it is a GTK Assistant window rather than a Windows Wizard window, so it looks different.

Is there a way to make the system names pull from the System theme in random order, instead of alphabetical order? I'd swear there was supposed to be a check box for randomizing it, but for me it always run alphabetically which is kind of boring, and as a result I manually rename every system.

In v2.5.1, the smallest increment of jump drive tonnage, 10t, rounds to the nearest hull size in increments of 50t when checking if it can jump ships. A jump drive rated for 370t can only jump 350t, while a jump drive rated for 380t can jump a full 400t.

Minor issue: ramming attacks seem to occur once every sub-pulse, i.e. five per five-second increment, rather than once every five seconds. If you turn off one second sub-pulses they go back to attacking once per increment.

(I don't think I've ever actually seen a ramming attack succeed, even attacking five times per increment, so this doesn't really matter much, but they probably should be consistent.)

The system themes are almost all created by players, so you can create an add your own. However, as the systems in a random game bear no relationships to known stars, any system theme would just randomly assign real star names to whatever system was generated.

Steve, this is a bit off-topic, but would it be feasible to add an option to use a system naming theme for Real Stars games? This would be a great help for multiple-player-race games with some player races as aliens and thus starting in other systems. It's a little weird when a player-controlled alien race from Zeta Reticuli transits their first jump point and discovers Gliese 182 or something.
