Benchmark Capital put $8 million to work with Swedish game site Power Challenge, the company will announce today. Power Challenge is a rich Internet application – a game that runs in java and plays very much like a video game. Users build and customize their teams and play against others for points and status. The quality of game play is high and is designed to push the boundaries between traditional PC gaming and online gaming.

Power Challenge, along with its sister site Manager Zone (acquired earlier this year), says it is adding 4,000 new players daily. They’ll use the cash from the financing to fund the development of new games titles, which are currently limited to soccer and hockey. The games are currently playable only on Windows PCs.

The company was founded in 2004.
