For classic it's Crushbone.
For Kunark it's a tie between HS and OS. With Chardok a close second.
For Velious it's a tie between ToFS and Crystal Caverns.

Classic: EC Tunnel, Oasis (Spec Island, underwater goblins, a giant pissed off crocodile, and pumas that run out of the ocean to attack you. It has it all :)
Kunark: Frontier Mountains
Velious: Great Divide I guess. I never spent much time there.

Classic - Lavastorm Mountains, no really, I like running there at night with the eerie music
Kunark - City of Mist, cause its kewl
Velious - Temple of Veeshan

Kedge and South Karana are my favorite places in the whole wide world.

Lower Guk Live side
Chardok
Western Wastelands !!

Live side misses out on the lguk love. Definitely an underrated section of the zone.

fyi saying you like Live side over Dead side officially makes you a hipster wood elf, just sayin

Oh I definitely prefer dead side. And I was about to make a hipster live side meme and post it here, but the site is nonresponsive... :P

I ammend my statement for Velious.

Sleepers Tomb.

blegh other than loot, *dislike!
