Pretty sexy game, specially if you watch it with graphics in ultra high =D
Dwarf player should have used undermine offensively. I hate seeing undermine used only to knockback a few units. Waste of insta winning potential; cast behind enemy fort when he's busy and you can clean a base (or insta win the game with earthquake and the 3 heroes against fortress)
Btw, this is a good replay for those who cry about Elves strugling against dwarf middle-lategame.
