I've got good news and bad news for fans of Capcom's Street Fighter games.
First, the good news: Street Fighter IV has begun to appear in American arcades (despite the ongoing death of the traditional, non-pornographic, non-booze-filled arcade). The game will eventually see release on the Xbox 360, PlayStation 3 and PC platforms, but purists insist an arcade cabinet is the only true way to enjoy these sort of pugilism simulators.
The bad news? According to EventHubs.com's handy cabinet locator page, none of the locations are even remotely near Portland, Oregon. The closest confirmed machine is nearly 1,000 miles south in the city of Walnut, California (though reports have trickled in of a cabinet only 314 miles north of us in Burnaby, British Columbia, Canada).
If you already had plans to travel to B.C. to smuggle prescription drugs for your grandparents, I heartily endorse the idea of stopping by and playing a few rounds on the theoretical SFIV cabinet -- the game really is that good -- but I can't recommend going to Southern California for any reason.
