Sega only makes games now, and does so for all systems. The ESPN games you are refering to are made by Sega by the way. They used to be known as "Sega Sports" games, and had titles like "NBA 2K" "NBA 2K1" "NBA 2K2" "NHL2K" "NHL21K" "NHL2K2" etc. Sega realized this was confusing and hurting sales, so they teamed up with Disney/ESPN to rebrand the games. So basicaly they are they same classic Sega sports games that most video game players know and love. Sega has always been better at making games then consoles (Sega CD, Sega 32X, Game Gear, Dreamcast), so mabye it's better that they quit that market.
I remember spending more time in that old Innoventions section back when I went there as a kid, then in the rest of EPCOT. No insult to EPCOT, just found the games addicting.
