Ok, the final levels weren't easy, but not insanely hard either.

And sometimes you needed to take control of a creatures to properly beat a level...DK rox0rs. I loved how you had to keep the reaper seperated from the other creatures because he was a homocidal maniac who went cuckoo at the drop of a hat.

Or how some creatures simply didn't get along.
Bastard horned reaper was often more trouble than he was worth. Even if you made him a private room with food, training facilities and bed and locked the door he'd sometimes broke out and started killing your other minions. The fact that I used to slap his ass around for not listening probably didn't help.
He sure knew how to fight, but you pretty much had to let him go at it alone every time...before you knew it he would be teamkilling.
No matter. It's dead now. Yay for EA's Chinese gold farmers (REAL gold farmers).
