This is my 2cp about the new Rebellion beta.
1. There is a bug in the random map (small), where it gives you two stars, as opposed to the one it says it should have. I didn't see this in any of the Known Bugs areas.
2. The interface is a tad bit cramped on 1024x768 resolution. The Menu button is a little overlapped by the Empire Tree management, and the Black Market is a bit scrunched. Nothing major though.
3. On a much more positive note for the devs, in the "minimum requirements" section in the stickied thread, it says minimum 2.3 Ghz Core Duo. My 1.86 Ghz Core Duo (Yes, my laptop is VERY old) runs this fine, on all settings low and smaller maps. Very good work overall.
I'm very much looking forward for future Beta updates and releases, Rebellion is living up to my expectations so far.
