Ah, interesting. I loved the heck out of the Exile games but I was unaware of details like this. I didn't even realize Exile I/II got graphics updates.
Interesting -- I actually see three different versions of the splash screen at that first link! (One with red text on a gray background and 1.0 graphics, one with blue text on a gray background and 1.0 graphics, and one with gray text on a gray background and 2.0 graphics.) There's also two different 3D-rendered splash screens.
