FF7.
My dad rented it, we didnt have a memory card.
I played upto when we leave Midgar, got destroyed by the snake in the desert.
We went out and bought a memory card, and FF7 soon after.
My parents started having some bad fights. and my sisters and I would sit in my room and I'd play FF7 while they fought. We played the whole game this way, and I remember not wanting to beat the game, because my parents were still going through that rough patch.
Eventually I discovered all the side missions, like killing the Weapons, and raising chocobos, so we did that for awhile.
It was interesting, and challenging, but eventually everything was done, except for the damn Crater.
I popped the game in one night, all of us determined to finish it, when we heard a loud bang in the kitchen.
Long story short, Mom and Dad split up that night, and it took a few months for all of us 3 kids to be together again.
When we got together, though, after just chilling out, my older sister told me I had to beat the game now.
So we did.
Mom and Dad never got back together, my mom ended up stealing my little sister and myself, and we travelled all over Canada and America(We are Canadian), and eventually I ended up in Australia. I see my sisters every few years, we still talk online and through skype a lot.
But thanks to FF7 we found out a few things we all had in common. My sisters now play games themselves, albeit waaay less than I do, but its something we can still talk about.
