Microsoft had a good summer, according to the company's summary of Xbox Live events. 1 vs. 100 reached nearly 3 million gamers during its beta season by Microsoft's estimates, and the Summer of Arcade Xbox Live Arcade promotion enjoyed a reported 200 percent growth in revenue over last year's sales.

While Microsoft has already relished in Metroidvania success, a press release claims that Trials HD and Marvel vs. Capcom 2 also performed well in first-week sales; and both titles join Shadow Complex in the top five bestselling week-one XBLA games of all time. Sales were no doubt boosted by a cloudy economy that kept folks indoors and looking for inexpensive entertainment. Microsoft capitalized, too, by raising the average price of its Summer of Arcade titles.

During last year's promotion, three of the five Summer of Arcade games were priced at $10, but this year, only two of the five were $10 -- the other three costing $15 apiece. (It's unclear if Microsoft counts Battlefield 1943's sales toward revenue growth; the $15 title was not technically part of Summer of Arcade this year.)

Microsoft also saw success in its bold, new free entertainment department. 1 vs. 100 averaged more than half a million users during each of the game show's live sessions. According to Microsoft, the game's near "three-million" downloads within its 13-week availability places 1 vs. 100 within the top ten downloads in Xbox Live history. If we've learned anything on this gloomy fall morning, it's that people like summer gaming and Microsoft has way too many "top" lists cluttering up its offices.
