The 35th anniversary of Sonic the Hedgehog is arriving later this year, and one of the ways that Sega is celebrating the event is a new ARG game called Chaos Hunt. Fans have been invited to hunt for some missing Chaos Emeralds, but players should probably check out the fine print before they take part in it.
As noted by user Luna Leo on social media, the terms of service for Chaos Hunt requires players to agree to AI model training and to sharing their details with third-party AI vendors.
Disappointed, but not surprised, Sega is requiring consent to AI model training in the terms of services to join on the hunt. Always read the terms you agree to friends.

The terms note that “We use reasonable efforts to prohibit [third-party] providers from using any of your personal information for the purposes of developing and improving their AI models.” It also adds that the third-party providers have to secure and protect the data they collect from players.
As part of the event, Sega released the following video featuring Sonic Creative Officer Takashi Iizuka’s in-universe announcement that the Chaos Emeralds were stolen by Sonic’s nemesis Dr. Robotnik ahead of the opening of Club Chaos.
Three grand prize winners will win a trip to New York City to join the fun at Club Chaos. Everyone else can purchase tickets for Club Chaos starting on August 28. The other prizes in the Chaos Hunt game are listed below:
Leblon Delienne statue
Lego Sega Genesis
Sonic 35th anniversary letterman jacket

Sonic 35th anniversary plush
King Ice pendant

Sonic video game bundle
Additionally, Sega is teaming with iam8bit for 35th anniversary Sega Genesis cartridges for both Sonic the Hedgehog and Sonic the Hedgehog 2. Meanwhile, Sonic Racing: CrossWorlds is going to feature crossover collaborations with Teenage Mutant Ninja Turtles: Mutant Mayhem, Godzilla, Avatar Legends, and even Neon Genesis Evangelion.
