The street dancer and RuneScape fan recently visited the Jagex studio to help create a new dance emote for the massively multiplayer online RPG.
"Visiting Jagex is a dream come true, and helping to create the new dance emote for RuneScape was a real highlight of my day," Sampson revealed.
"I love RuneScape so it really means a lot to me, knowing that something I've created will be part of the game is really something special."
Sampson, who has appeared in the movie Street Dance, as well as television shows such as Waterloo Road and Mount Pleasant, has been a RuneScape fan since he was 11, and is still an active player today.
The George Sampson dance emote will be added to the game during a future RuneScape update.
RuneScape is a free-to-play massively multiplayer online role-playing game launched in 2001. It is recognised by Guinness World Records as the world's most popular free-to-play MMORPG.
Developer Jagex unveiled a new website and logo for its popular free-to-play online role-playing game last November.
The redesigned website contained an array of new tools and features, including a new community-editable RuneScape wiki and a dedicated events section.
It welcomed a brand new 'Troll Warzone' tutorial area earlier this year, and even celebrated the recent Diamond Jubilee.
