Nowhere Else and Beyond

Nowhere Else and Beyond is a web based multiplayer RPG and PBBG which allows players to explore exotic locations in 2D, interact with other players (a player can see other ones on the map as well as in the town, can chat, trade, and play mini-games with them), collect and play an in-game card game and build their own island and create quests within it.

The game is completely free, besides for optional items. It also doesn't need any traditional registration as providing a username and password is done within the game by talking to an NPC.
