Let's do Red Side:
Sharkhead Isle vs. St. Martial
Go!
Preferred Sharkhead between these two.
I loved the really dark and disturbing atmosphere of the pit, and hellforge was awesome so I'll probably have to go with Sharkhead.
Although St Martial was also really nice and I used to love watching the crab spiders fighting in the streets, the Giza was amazing too
Sharkhead wins!
