When I was much younger during the NES/SNES vs. Sega days, my Mom was so sold on Sega for some reason. Our family had all the Sega stuff. I still remember how our Sega was the large one, and not the smaller new one, so it did not fit right on the Sega CD console and looked weird. The Sega CD was my first introduction to Tactical RPGs with the game Dark Wizard.
