I like Mage Towers. The atmosphere and OST in the earth and air tower are great, and overall it´s a nice addition to have another faction here. It seems they planned more with the Hand Brotherhood but unfortunately it was cut from Thief 2.
But back to Mage Towers.
It´s not that challenging, but still fun. I would have wished for loot in the elemental towers(not counting arrows and such stuff) but overall I´m fine with that.
It´s also fun to steal the medaillon from Captain Regalio - hehehe. I let the taffer sleep and steal it right away from under his nose.
So, a relaxing level before we have to deal with the annoying Lost City.
