1: Chessmaster's Tower

Definitely one of the most original areas. I just love the whole chessboard setup. It's an area you want to visit once in a while from lvl20 to 51, which only adds to it's coolness. I just love that parrot and what it's stands for (From what I hear I'm the only one).

2: Lost Elven Vaults

I loved getting the hang of this area, the riddles are fun and challenging.

3: Organia

I've always loved the concept of being in a dreamworld. It's especially nice if it's as worked out as Organia is.

4: Shadar Logath

I loved the combination of being a great ranking area and being dangerous, if you're not carefull. Mount Calandryl is similar in effect, but just doesn't seem to give me the same excitement. I miss this area. (the gear was nice too :))

5: Emerald Forest

I love the diversity of creatures and sub areas in there. An area with a lot of atmosphere.
