StarCraft II: Wings of Liberty
Sean started casting with Brood War game replays. With the release of StarCraft II he moved away from competitive playing of his own and focused on full time streaming. He regularly casted 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.

Magic: The Gathering
In May 2013, Plott competed in a Magic: the Gathering Pro Tour as a wild card selection. The same year, he began producing a YouTube series about the game called "Spellslingers." In each episode, guests such as Felicia Day and Grant Imahara take on Plott with the hope of emerging victorious in an all-or-nothing match, while teaching the audience the tips and tricks to become better at the game. "Spellslingers" released the final episode of its 5th season on December 5, 2018.
In January 2017, Plott began a weekly series in which Dota 2 personality Kevin "Purge" Godec teaches him advanced gameplay concepts of the title. In August of the same year, he served as the co-host for the premier Dota 2 tournament, The International 2017.
In September 2013, Plott joined a new game company known as Artillery. At the company, Plott worked on the real-time strategy game Guardians of Atlas, which opened to beta testing 2016.
