I've won by conquest and by alliance and at difficulty levels up to "hard" and always rated as "Janusk". I don't *think* I was playing that badly
Think it needs work.
But generally I really like the idea of a top-score list. Properly implemented it can keep me coming back to a game over & over to see if I can beat my all-time best. (My best with MoM was was more than a decade after it came out, and I got one in the top 10 just a few weeks ago, while waiting for the Fe beta to start).
