Blame the guy that brought up SSB in a fighting games topic.
I'm not saying that SSB doesn't qualify for this topic, but if someone is defending themselves mentioning a non-fighting game in a fight game topic is obviously going to use this excuse: "Well, when I saw those people talking about Super Smash Bros, I momentarily forgot that this topic is exclusive to fighting games. Since I am always forgetting how Super Smash Bros technically qualifies as a fighting game, I see someone else mention it, and cannot help but assume that this topic is open for discussion of any game genre I may happen to be playing."
