Wii Sports dominated the evening, winning six out of the thirteen categories – Gameplay, Casual, Innovation, Multiplayer, Sports, and Strategy & Simulation. In this game of universal appeal, players use the remote as a tennis raquet, golf club, boxing glove, baseball bat and bowling ball to emulate the actions in real life sports.

There were two rounds of voting for the awards; in the first round, BAFTA games members and industry experts cast their votes on line for the 1000+ entries received. The top-voted titles were then sent out to jurors, while those pre-release titles which were ready in time for the judging process, were played on test units in a secure room at BAFTA by every juror, over a period of some five weeks. Once every juror had played every game, each jury convened to create the 6 nominations in each category. Other late releases not ready for this year’s Awards will be eligible for next year’s.

Whilst I totally understand the merits of Wii Sports, I'm not sure it deserves to win all 6 of those, but nevermind, great news for Reggie!
