So, I submitted this idea to the Xbox feedback program and I hope you would upvote it
Speaking from my own experiences, I like playing games with other people but I find it VERY difficult to get over social anxiety and shyness of being not good enough, and I image other people would have this too. Also for example if you’re not very good in English or have a condition that makes you need take breaks or need help with specific things.
If you don’t know, LFG stands for Looking for Game, a function on Xbox Live where you can set a beacon of sorts to find people to play a game with you. It already has tags like #notrashtalk, #newplayerswelcome or #adultsonly so I think this would be helpful and a worthy addition.
