I'm sure this topic has been done a thousand times now but hey ^.^

FFVII, with my Cousin, who owned it. We played through it together. In other words, he did all the important story-driven bits and when I borrowed it all I could without dying was training But hey, that was 10 years ago XD
I also remember he thought it was over when we blew up the first reactor Much lol'ing. And he thought it wasn't that good til I forced us to both play it cos it looked SO. COOL.
