Veteran professional wrestling journalist Bill Apter chronicled Sting's career in a piece for WWE.com on February 19, 2014, wherein he stated that Sting's "best days may still be yet to come". He appeared in a WWE Network production on April 15, 2014, sharing a story of his former tag team partner The Ultimate Warrior, who had recently died. This marked Sting's first non-archive appearance on a WWE-branded show. Sting was a prominent contributor to the documentary film "Warrior: The Ultimate Legend", which aired on the WWE Network on April 17. The following day, online retailer Zavvi announced the WWE Home Video DVD and Blu-ray "The Best of Sting", which was released on September 23, 2014. On July 14, Sting appeared in a vignette on "Raw" to promote the video game "WWE 2K15", in which he was featured as a pre-order bonus character in both his 'Crow' and 'Surfer' (pre-1996) incarnations. That same day, WWE began selling official Sting merchandise. On July 24, Borden made his first public appearance for WWE, in full Sting garb, as a surprise guest at the 2014 San Diego Comic-Con International. The event was held to announce WWE's upcoming line of Mattel action figures, in which the company's first ever Sting figure would appear. Prior to that appearance, Sting gave his first interview with WWE.com, which was released later that day. On August 4, WWE announced Sting as a guest on the "WWE 2K15" "Roster Reveal" panel, which took place on August 16 in Los Angeles.
