Thanks for the response. Now that you mention it, I wonder if I'm really looking for something CivUP+GEM specific. Granted certain bonuses may change, some attack/defense values, some wonder/building stuff, etc.
But overall how a good player micro's, how a good player handles an expansionist AI civ, how a good player manages gold and happy are the kinds of things I think I'm looking for. Perhaps I should just be watching any lvl6+ videos and get what I can get out of them. But even if someones using an old version of CivUP+GEM I'd say the same thing, some of that stuff would come across and it would be up to me to make adjustments, and that's ok by me.
