Has there been any effort anywhere to catalog changes made in the general game play and such between SC2 and UQM? If so, is the list anywhere? I know in finally getting to do a "lazy" playthrough of UQM that I've found a lot of little changes (mainly with the lander - which was QUITE annoying, but also with how some of the ships work).
Also, the funny thing I found (which may or may not need to be specified as a bug) from landing on seismically unstable worlds is that earthquakes will stop stunner shots! I don't know if that was the actual intention or not, but it seems kind of on the screwy side.
