TinMausSubreddits you are going to miss?
MeatCastleI'll miss all my niche gaming subreddits. Path of exile, incremental games, and I even liked keeping an eye on the gacha gaming subreddit. So many more to mention like r/gamedeals, patientgamers, many more individual game subreddits.
SevIncremental games is a good one, yeah. It's a space with a lot of shovelware and abandoned / incomplete projects, so it's soooo helpful to have a place to find out about new good ones or ask for help when you're stuck on something niche.
