What's The Best Video Game From This Decade?

In honor of yesterday's release of GT5 Prologue we've been holding on to a few video game QOTD's. Monday, we asked you about your favorite racing video game from the 1980's, yesterday it was racing games of the 1990's and today we're looking at the post-Y2K years when, despite the fall of civilization and technology, we have some pretty kicking games. By asking this question today we also give anyone insane enough to buy GT5 yesterday and play it the chance to chime in. But maybe there are some Project Gotham fans out there?

Perhaps someone will admit their love for Mario Kart Double Dash or maybe an arcade game like Carismo. If you own a Wii you can race through British streets in classic British cars in Classic British Motor Racing. Personally, we're partial to the arcade version of Tokyo Cop, which allows you and a friend to chose down the bad guys in a Kei Car. So many to enjoy, so much actual real person work to do. What games are occupying your time now?
