Okay, I watched the game and here is my review ... I'll try to say things you did well also, but i'll mostly concentrate on things to improve
Firstly, I think you played pretty well. I'll start off with early economy ... you're early economy was abit unbalanced- anything more than 5 dwarves in Archaic is overkill (unless you're going Heimdall) ... but even with Heimdall you can still have 5 dwarves and be fine ... you ended up with a slight gold excess in Classical, but it worked out to be not too big of a deal. I think you would have done better though if you had a better Classical time- you ended up near 6:00 which is crazy in an Odin vs. Odin game . I know Midgard is definately one of the hardest maps to balance you're economy on, so you have to judge whether you got enough fishing to support you're advance in good time or if you'll need to put more villagers on land food ... IMO for this fishing situation you should have had 5-6 on land food, when you only had 4. In an Odin vs. Odin game, or pretty much any Norse vs. Norse game, I always aim for a sub 5:15 classical ... which means I usually hit the button anytime between 4:00 and 4:15. If you're opponent doesn't do the same (which he didn't here), you have a good head start in raiding him and on the sea battle and can usually end up either denting or crippling his economy.On to militarily now - IMO its always very difficult to know what to do on Midgard. If you get an opponent who goes all out on water while you're going for a land army, you can usually cripple his economy before hes even got an army out. You decided to do a mix of both though, which kinda sorta worked out OK. The mistake I think you made is this though .. when you hit Classical you made Longboats, but you had them sitting there idle. In my experience, and also what i've seen in pro recorded games, is that its best to send the ships in immidiately on Midgard - especially if you're planning a land attack. You could either distract him and make him think he needs to put up a big fight on water so that he ends up sinking all sorts of resources on the sea, or dent his economy if he wasn't planning on fighting for the sea at all. On the land approach though, I think one of your biggest mistakes of the game and waste of one of Odin's best advantages was not using you're ravens as much as you could be. For the majority of classical, my Ravens are always moving around. Intel is one of the most important things in AoM, and thats what Odin's ravens give you. You should have been moving them around to food sources, moving them along the coast to spot his docks, moving them overtop of unclaimed settlements (around the 13:00 mark you're opponent took one of the forward TCs and you didnt even know he did it and also put up a Hillfort). When you get tired of microing them around, park them each overtop of you're opponents nearest gold mines outside his base ... I think you had one sitting over the water and the other carefully watching some trees outside your base for most of the game A mistake that you made, and even I find myself making on occasion, is not having enough raxes (or thinking you do but you dont ) .. during a key battle for the center of the map, you had two barracks and two Hillforts ... by this time in the game (17 min mark or so) you should have had 7+ raxes ... I know its happened to me where you think you have enough, then before you know it he's knocked down afew and you're down to two raxes trying to keep max population Urh, also, before this happened, you had an attack on his base going (you're Walking Woods was in there and whatnot) ... had you concentrated the attack abit better (knocked down some houses, then the front towers, then the temple .. etc) and made more siege (or protected the siege that you did have) you might have done some damage. Also, in the middle of this attack you decided you wanted to claim the settlement that was behind your main one ... you sent 10+ units to go build it! 3-4 is plenty, and have the rest continuing you're attack. He cast Walking Woods during one of you're fights, and it ended up going after you're economy .. it did quite some damage before you were able to take care of it and you're economy was pretty crippled. You had three Settlements claimed at this time, but were only making villagers from one of them! You could have had farms up at the other two as well, which is what you really needed (food) seeing as how both you're MUs cost food as well.Near the end of the game when you took control of the map again, you attacked head on right where he was setting up for it! Fimbulwinter is best used at the same time as an attack on a TC, and he had one wide open down in the left corner .. you could have easily taken that from him, which would have raised you're pop by another 20 points and decreased his by 20, then attacked his main base from that side (you could have claimed the TC and thrown up one or two Hillforts by the time Fimbul is over), which had no defenses set up. He started running around wildly at the end, knocking down you're TCs .. but it was GG by then, you should have sent some cavalry over to try and take care of him there, but left the most of you're army leveling his base. He was done, he had no economy and no TCs ... but meh it worked out so oh well At the end of the game (before he attacked you) you had like 18 on food, 11 on wood, 14 on gold ... this isn't enough 25ish on food (even more when going Freyja/Njyord for food MUs) , 14ish on wood and 17ish on gold is more like it .. it worked out OK in this game, but just saying that that econ won't do in most games You wouldn't be able to keep up mil. production ...anywho .. I think I covered most aspects of the game Hope I was helpful ..
