Challenge Games Raises Another $10 Million. Well Played, Sir.

Browser-based fantasy game startup Challenge Games has raised a $10 million B round just a couple months after raising its $4.5 million A round. Globespan led the round. Sequoia Capital, which led the last round, also participated (Sequoia partner Roelof Botha is on the board).

Challenge is behind the online role-playing games Duels and Baseball Boss. Both are addictive, and are designed to encourage the trading of virtual goods (better swords, better short stops) to help players improve their chances of scoring higher in the game.

The company is about to launch a new game called Warstorm later this month, and will use the proceeds to develop even more games, expand into Asia, and possibly acquire other game shops.
