Attended a panel today about the future of video gaming, media, interactivity etc. and one of the panelists mentioned Virgin Gaming. Apparently, in around 30+ states within the USA, it is legal to gamble on video games, because they are a "Skills based" feat, as opposed to poker and blackjack, which are "luck based." SO, Virgin has built up
Virgin Gaming to house your video game gambling vices, if you so choose to do so.
I myself haven't used the service yet, but from looking around the site, they've got almost every major sports game up there, and are starting to flesh out their adventure genre with Assassins Creed.
Hopefully one day they'll have fighters up there a la Marvel vs. Capcom, but till then, enjoy adding even more intensity to your Madden games.
