I wasn't sure where to post this, please relocate to an appropriate area if there is one...
I noticed that occasionally the other races don't appear to 'start' right away... or at all. The graph charts show no sign of activity until I've expanded 4x+ the other races territory and have progressed to a point where unless I'm ganged up on I'm going to steamroller some races. The production/research/influence charts show me high above everyone else as well, some small blips of it showing something other than flatlining but nothing like what normal games look like (I only play on challenging or higher difficulty)
I don't have TA yet, just GC2:DA, hope that detail helps shed some light on this. I'll reload the game I was playing that this last happened on and pull out more details if that's helpful too.
