In all my games it all goes pretty much the same. Challenging is my average skill level (although I have successfully beaten it on all other levels). However, no matter what skill level I play, the AI always takes very long to get large starships.
Everyone gets Medium about the same time, which balances out the power. I stick with medium for a few years but then research larger designs, and that's it, I've practically won the game, my military rating shoots up and no other race dares challenge me.
This happens 99% of the time. 0.5% I am wiped out before I get medium and the rest at least one race is brave enough to challenge me.
Is this a bug in the AI, or am I doing something wrong?
Edit: I should probably mention I'm on v1.2
