The IGS video is worth a watch, though. It explained it a bit better than I was interpreting from vids of it.
EDIT: Played the first one for about five minutes. I already have some things I noticed.
1. The graphics options on the first one, at least, are absolutely horrible. The highest resolution I was allowed was 1280x960.
2. The controls are abominable. Rebind them as soon as you start the game up.
3. Combat is incredibly simple. Given it was described as a "roguelike" of sorts, though, I guess I shouldn't be surprised.
4. Combat training doesn't do much...training. It's pretty much just a shooting gallery with what I can only assume is the game's weakest ship.
