At one point Spamt had a whole 10 population free for his army and managed to hold off a 100 pop army for another 1/2 hour. Mercs absolutely carried this whole game
When games go on for this long it's easy to get tunnel vision and forget how important cutting villiages and changing up your army composition is. Because you feel like you are on the verge of winning/losing so you feel like you must focus all on micro all the time. But taking a step back and rethinking what you're doing is usually the best thing to do in my experience.
A couple more catapults in that rock drop a bit earlier may have been enough for Spamt to come back. Taking out the main food TC would have been big plus the market if he could have gotten there
