I now have the latest 7a and 3c, and I'm going to enjoy both - the different styles are both interesting.
I noticed two ( very minor )things in 7a ( one of which I think persists from 6 ):
The Amazonia Temple of Victory buildings have, under description," #PLACEHOLDER DEFAULT ", and the final one "Warning, this message should not appear"
The Egyptian legion-clone ( in custom battle ) is called " Unlocalised placement text "
As I say, unimportant details.

Regarding Alex ( which I liked but probably wouldn't play again ), it is one of the programs that, when uninstalled, still show up in the Windows control panel list of programs to remove and yet, when selected for removal, cannot be found. Indeed a search of the disc can't find them. Ghosts I tells ya!
