Sega has a really fun history to research into, from console ideas to their place in the Japanese arcade market.
For a time, they were really innovative, even if most of it didn’t work out the way they had hoped. Just throw it at a wall, see if it sticks.
This is a stupid one, but as a kid, E.A titles always stuck out to me because they had these unique cartridges. They were taller, and had this weird yellow tab on the side. Turns out it was to bypass some restrictions Sega had in place, but as a kid, I just thought it was neat that they looked different. It made me want to get them just to have more cool carts.
