That last night elves level was a bitch to survive. Took like 3 tries before I figured out a good strategy. After the human encampment was destroyed and we were pushed back to the elf level, I kept buying land mines from the goblin merchant and laying them all over the place. Combine that with the rooted tree defenders (i forget their names) a ton of archers and my two heros, I was able to hold them off with the orc base all the way down to 4 minutes. And then by the time they were ready to attack my main night elves base, it was too late for 'em. w00t!
I have to agree though, compared to the other badass cinematic sequences in the game, the ending was WAAAY too short and uninteresting. Pretty surprising from a company like Blizzard. Some of the things in the credits were amusing... but I still would've liked a better ending.
Anyway, I'm glad I finally took the time to beat the game, cuz now I can move onward to the Frozen Throne come July 1st.
