OK, played against this Odin guy and was surprised to see him advance through Heimdall.
We had a big fight over the water which I initially won, but then he advanced with Njord and with 4 Krakens he wiped me out of the sea.
Meanwhile, I realized what was going to happen and abandoned the sea, turning to farming for food.
During this time, I advanced from both sides of the coast, making FB on one side and claiming his 3rd TC on the other.
We had a few scuffles on land, which I managed to win and then -after I advanced to Heroic- when he saw my cavalry coming and a force of Valks and Warpigs roaming around his base, he quit.
The different thing about this game, was that I've never seen an Odin advance with Heimdall and wasn't exactly sure how to deal with it, so we both made lots of Hersir.
The game has a few nice battles, plus the abandoning of the sea by the Thor player, which usually spells doom for any player on Med.
