I am an ancient, withered husk of a man so my version of this was probably Neopets, it was one of my main obsessions as a kid to where i would play spinoff things like picrel. The furums on this game were my first experience actually talking with other people online so i guess i was exposed to furry like stuff at least that far back, and i was definitely doomed as soon as I played shit like Roblox and TF2 that had a fluff ton of furries on them
