Sean began focusing on casting games with the release of StarCraft II while moving away from competitive playing of his own. He regularly casts for the Major League Gaming Pro Circuit, the seasonal DreamHack LAN, the Intel Extreme Masters' Cup, the North American Star League, and other tournaments. In addition, Plott was one of the stars of State of the Game, where he discussed current events within the StarCraft community along with other highly regarded members of the community, including the show's caster J.P. "itmeJP" McDaniel. Plott has not played StarCraft II professionally since 2010's HDH Invitational.
He was a primary caster of the BlizzCon 2011 tournament, from the regional invitational qualifiers to the finals at BlizzCon 2011. He has also cast a number tournaments he himself co-organized, including the After Hours Gaming League  and the SC2 beta tournament, King of the Beta. In 2012, Plott appeared as a caster for the Red Bull LAN and MLG's Winter Championship.
Started in 2009, the Day Daily is a daily webshow based around analyzing professional StarCraft games. Initially, the Daily was a webcast focused on high level StarCraft: Brood War play. With the release of the StarCraft II beta, the focus of the show shifted from Brood War to StarCraft II.
In Daily #100, Sean talked about his life of StarCraft, and how it came to define him as both a gamer and a person. Plott, in Daily #400, took a more general look at the art of learning and self-betterment in any field, and took part in the SOPA blackout of January 18, 2012 in Daily #404. On the Day Daily on May 11, 2011, he announced that he would be pursuing StarCraft II full-time.
In early 2013 Day created a show called Day's Day Off, in which he plays through "non-StarCraft games" - these take place for a few hours every Friday on his TwitchTV channel; the day's output is then uploaded to YouTube over the following few days in approximately 30 minute length segments.
Day TV currently streams Hearthstone three days a week, with adventure games on Mondays, and other games on Fridays.
