I'm going to say this was my subconscious fighting against the vote rigging by the Smash fans.I see the headlines now: "OP in not calling Smash a fighting game controversy".
A lot of them listed Smash Bros for 3DS and Smash Bros for WiiU even though the OP was amended that a game on multiple platforms can't be listed twice.
And I would have gotten away with it too... ;-)
