Sonic Adventure. It’s just a comfy game and I love the story. Yeah it’s cheesy Shonen but it’s just fun. My favorite classic game is Sonic 2 because I played it the most on my Genesis growing up.
Being a lolcow is what you do, not what you’re into. If you behave in a manner that makes people laugh at you - chimping out online, over-sharing, very public hypocrisy and generally having no filter - then you’re probably a lolcow. If you play Sonic games or whatever, that doesn’t make you a lolcow in itself.
Lolcow fandoms are really about overlap. Fandoms like Sonic, Steven Universe, My Little Pony etc tend to attract a lot of lolcows. They appeal to autists and other socially awkward people. Whereas a more mainstream adult show is far less likely to be overwhelmed by lolcows..
