Roblox
From Tardis Wiki, the free Doctor Who reference
Roblox is a massively multiplayer online game (MMO) aimed at children ages eight to eighteen.
Although almost wholly unrelated to Doctor Who, bar a few unlicensed fan games, in 2020 Roblox, in partnership with the BBC, released two avatar bundles based off of the Tenth Doctor and the Thirteenth Doctor, as well as a shoulder accessory based off of the Pting, and a back accessory based off of the TARDIS.
