I'm not sure if I saw it here or not, but with the EQ servers down I'm trying to remember the name of a game I played for a while. As the title says, it was web based. It was a very basic old style RPG, I recall the base being white. The main map was maybe a 4x6 grid and you clicked on the area you want to fight in or travel to.
I think you start on a mountain and talk to an owl that sends you on a task. There is a city area with merchants as well as sewer areas you fight in. There is also a guild area, which had a ball pit you could jump in once a day to get stat bonuses as well as a vending machine that gave stat items.
The names of mobs and quest texts were clever and entertaining. For the life of me I can't recall the name of it.
