For Undertale: Matpat lmao (Im not joking) in 2019 but back then in 2015 and I saw someone obsessed with it and originally thought that it was interesting but, had no idea what the game name was or anything…
For DELTARUNE: I saw it on the switch app store 4 free around 2020-2021 and noticed Toby fox made it and I was like sure this is going to be good and since then that's my lore…
