Famicom had a Disk add-on which didn't come to America, Super Nintendo was originally to be a Disc Unit helped by Sony (Thats how why Sony Launched Playstation), Nintendo 64 also had a Disc Drive add-on which also failed. SEGA wasn't the only add-on System.
I LOVE THE SIMS! I LOVE TO CREATE. I'm just surprised to see the Wii version being Open World.
