Service Games, formerly known as SEGA, is a game company currently specializing in games for all platforms and arcade machines. Over the years they have produced many consoles, including the Master System, Megadrive/Genesis, Game Gear, Nomad, Saturn, and Dreamcast, as well as hundreds of games. And of course, Sega's world-famous mascot is the blue blur Sonic the Hedgehog. Sega also produces different collectibles such as models and figurines.

Personally, I love Sega more than any other game company because they're the creators of my favorite consoles (Genesis, Nomad, Dreamcast) and games. I hope to collect more consoles and games in the future.
