Danganronpa was my first ever anime aside from Ghibli movies, and it was very fundamental to me becoming a weeb. I got into anime for a few years before I took a look at the community and the industry, realised both were toxic as shit and just stopped watching new anime. Persona 5 literally salvaged my mental health for years and it was massively important in helping me realise really important shit. Then playing the DR visual novels later, I'd say those two franchises really solidified my taste in games (which is mostly JRPGs and visual novels lol).

I don't know what else I would include to be honest.
