I suspect most of them were infants in the 90s. That said troons definitely played before the current crop of players, but I feel like a lot of them did prefer more "alternative" settings like Shadowrun and scifi ones. The current trend I see now is a lot of players who started with 5E and aren't really aware that a variety of settings exist, and are so influenced by Warcraft tier meme fantasy shit that they're basically unsalvageable, and use their character as a self insert the same way Chris-Chan is trying to, rather than as an interesting character to play that they came up with, like an unusual race and class combination, a character with a lot of backstory, stuff like that.
