Welcome to SportsNation! On Friday, ESPN.com's Playbook Tech blogger Jon Robinson stops by to chat about his ranking of the Top 25 Sports Video Games.

Ever since Robinson first handed the ball to Bo Jackson in "Tecmo Bowl," he has been mesmerized by the world of sports video games. He's been covering the gaming beat professionally for over 15 years, starting his career writing as "Johnny Ballgame" for GamePro magazine before becoming the founding editor of IGN Sports. Robinson co-wrote the book "The Madden Phenomenon," and his two latest works, "Rumble Road" and "WWE My Favorite Match," were released by Simon & Schuster in July 2010 and July 2012.

Send your questions now and join Robinson Friday at 2 p.m. ET!
