Walkthroughs for custom maps.

Tell me, is Metataxер significantly more complex than Xiedu and The Lord of the Rings from Season? I just watched a walkthrough of Metataxер on YouTube for a couple of days, and I remember seeing a few battles, although I don't even know from which stage of the game. It seemed quite intricate to me. If the difficulty is roughly the same, I might give it a try.
