SEGA is happy to say that both the Sonic and Puyo Puyo series’ have reached their 20 year anniversaries. Quite a big achievement for both franchises. I had no idea that Puyo Puyo was that old! What’s SEGA doing to celebrate these anniversaries? Well, they say that they have a number of ‘projects’ in the works, but never go on to say exactly what they mean by projects. We’ll just have to keep tabs on SEGA, as well as the special Sonic 20th anniversary site!
