I think that "Adventure Forward: Crown of Shadows" should be added because it is a speedrun-able game. Therefore there is only a Demo, the full game will be (probably) added on 1/02/2021 (read game description).

To the mods: If you are reading this and are making sure if the game is speedrun-able, check this link: https://web.roblox.com/games/5961562771/Adventure-Forward-Crown-of-Shadows-DEMO

Have you actually tried requesting a game for the roblox series?

Gameboy9917, how do I do that? Plus the message is a request for the game.

Right above your last message is the link to do that.
