Out of the blue, Sega has redesigned their website to go with their new 3rd party look. There’s tons of new sections including a section for each console Sega supports (i.e. all of them) and a large history section on what Sega is and was. They haven’t forgoten Sonic either, just check out the backround. There’s so much new, you’ll just have to see it yourself at
