Reminder to those planning first moves: Mongols are expanionist, so you get a scout. Though the first move is only going to be a single tile, after that you'll get to travel 2 per turn.
I'm guessing this COTM won't feature the Ordu Archer, Korchin Horse Archer, Turghaut Cavalry & Bagatur Hordes we saw last time the Mongols were featured.
The good news about the UU is that these mountains won't bother him and you don't need iron to build it. Aside from that it stinks. A cheaper knight with less defense.
Without seeing the mini-map or knowing the level (I hoping it's monarch or below from the starting location), opening moves aren't really decide upon.
One more little tidbit about the Mongols, they start with two of the cheapest opening techs so you'll be in 2 for 1 trades (if at all) for a while.
For those who don't peruse the HOF very often, the Mongols are one of the least used tribes, which kind of highlights the weakness of the tribe unless a tailored situation appears.
