Have you ever played a videogame with the main initial hook being one character? I know it sounds odd and silly but still, how many times you got a game because of one character? (If the rest of the game keeps you hooked up it’s another subject, but I mean the initial hook)
To me it was Final Fantasy VI because of Kefka Palazzo, Team Fortress 2 because of the Spy, Ultra Street Fighter IV because of Elena, Dota 2 with Lina, Skullgirls with Peacock, New Super Mario Bros. Wii because of Iggy Koopa and so on.
And admittedly I’m tempted to play Blazblue just because of Yuuki Terumi (technically speaking two characters since Hazama it’s also included here)
