How much it costs: £220+ (new) Sonic Generations, as fans of the Blue Hog know all too well, is one of the only Sonic titles released within the last decade that's actually worth buying, so if you're a fan of the series and have a penchant for buying luxurious collector's editions, it may as well be this box of goodies that you throw your money at. Inside, you'll find a celebratory art book, an adorable statue featuring both Classic and Modern Sonic and a commemorative golden (not real gold, obviously) ring to remind you of all those hours you spent collecting them. Sorry guys, it's not small enough to double up as a cheap wedding ring.
