Not enough video game communities. I think that was a huge part of Reddits initial success. Even to this day I still search "Problem + /reddit" on google whenever I have issues in a game. Reddit often holds the core community off a video game. It's often detrimental to a games success to have a Reddit community. Lemmy has communities for some games, but they are mostly inactive or have only 10-60 users. So don't even have the latest patch notes posted.
No worries. Feel free to start a new thread there if you feel so, there might have been new communities in the meantime, and it's always good to have a refresher once in a while
