The franchise is known for its eccentric and passionate fandom, which produces unofficial media including fangames, fan fiction, modifications and ROM hacks of existing games, fan films, and fan art. Caty McCarthy of "USGamer" noted that many fans have continued to support the series in spite of poorly received games like the 2006 "Sonic the Hedgehog", and credited the fandom with helping maintain public interest in the franchise. Notable "Sonic" fangames include "" (2013), set between the events of "Sonic the Hedgehog 2" and "3", and "Sonic Dreams Collection" (2015), which satirizes the series' fandom. "Sonic Mania" development team included individuals who had worked on "Sonic" ROM hacks and fangames, while Iizuka said the character customization system in "Sonic Forces" was influenced by the "Sonic" community's tendency to create original characters. Summer of Sonic, an annual fan convention dedicated to the "Sonic" series and hosted in the United Kingdom, was founded by Svend Joscelyne and Adam Tuff and first held in 2008.
