Soul Calibur
Soul Calibur, often shorted to SC (in Chris's case, to SCIII, which is not to be confused with CSIII), is a sword-fighting game franchise created by Namco. CWC loves to create his enemies in Soul Calibur III and make pathetic videos of him struggling to beat them on the lowest difficulty setting.
Apparently he and Megan were dedicated players of the arcade version, too, judging by e-mails discussing the purchasing of horribly overpriced weapon and ability cards to be used with the arcade machine.
In addition, Megan was freaked out with Chris's "Megan obsession" which included Chris creating a character of Megan in the game.
In the Christian Weston Chandler's Adult Chronicles ad, Chris promises CWC and Sonichu-related DLC for Soul Calibur IV. With the most advanced boob physics to date this series has seen, the public at large would probably rather not see that pack come to fruition. (Unless Mary Lee Walsh is included, naturally.)
In the infamous facerape scene of Episode 17, Rosechu seems to duplicate one of Sophitia's special attacks from Soul Calibur II. (However, Sophitia cleverly performed this attack fully clothed, without clawing and zapping the victim's brains, and most importantly not shouting some of the most embarrassing battlecries in the history of feminism.)
