Am I the only one who hates it when people ask "Am I the only one"? No.
I hate it when people say stupid things like, "Am I on the only that doesn't care about Smash Bros.?" No, you're not. Stop thinking you're special. There are more people in the world that don't care about Smash Bros. than people who do care. There are lots of people in the world. Not all are gamers. Hell, even within gamers, there are plenty of people who don't care about Smash Bros., or Nintendo, or about how it sucks that Ganondorf doesn't use his sword, or other stupid stuff like that.
You're not unique. There's at least one person (I'm sure much more than one person) that has the same opinion as you.
