There are some years I started playing video games on a Megadrive, with the cartridge Sonic.C'est to find this excellent game that I bought on DS.Cette saga is complete .. .a real delight to find that all the characters! Some may find outdated, obsolete view, but for those who have known this friendly hedgehog, and for those who want to find out, do not hesitate, buy it (at Amazon, although course), you will not regret, a little freshness in a cruel world ...
