One Million Xbox Livers can't be wrong. At least thats what Microsoft are hoping. Starting this fall, Microsoft will launch the Xbox Live Arcade, an online service that will allow users to download a variety of "poker, card, trivia, and classic arcade games," according to Xbox Group Chief J Allard.

Saying it was targeted at more-casual gamers, Allard presented the Arcade at tonight's Microsoft E3 conference. Though he didn’t display any of the trivia or card games he alluded to, he did show off one of Arcade's retro games catalog, which will feature Namco classics like Dig Dug and Galaxian and PopCap Games' classic Bejeweled. Lesser-known, more-modern games, like Big Fish Games' Alien Sky and Feeding Frenzy, will also be featured, as will selections from Garage Games' catalog.

According to Xbox business dude Aaron Greenberg, Xbox Live Arcade games will cost around $10 each to download. CD give-aways will also allow XBL subscribers to sample Arcade titles for free.

At the testing session for this idea, participants where told games would cost between $5 and $10 to download. Most participants agreed that this seems steep, but many will probably atleast try it.
