Is it possible to edit a game request? I don't see an option too but I didn't poke around because I didn't want to withdraw it and send it to the bottom of the stack.

I want to edit the video link, because I made a better quality video. Does that even matter, or are the videos just there to prove the games speedrun viability?

I did try to find out some edition of the game request, but it's not possible... the withdraw mode is the only option... but before withdrawing the game request you can do copy+paste of all info of the game request... that would be useful so as not to write the whole thing again.

It wouldn't really be a good idea to allow game requests to be edited after they are submitted. Simply because its gonna take more time for site staff to track any changes made to a game request after its been submitted. Though, we are looking into methods that would allow users to add additional information without entirely having to reject and resubmit a game request, but it would most likely be on request of site staff only for now.
