For anyone who grew up in the 80s & 90s, Sonic was THE thing. This compilation encases all of the Sonic games, including Sonic Spinball & some other 'spin-off' games. It also features the likes of Ecco the Dolphin, Flicky, Columns, Bonanza Brothers, Alex Kidd & many, many more. If you're a bit of an achievement hunter, the majority of these are fairly easy to get & include achievements such as 'Get Rich - Alex Kidd: Collect 1,000 in currency', 'Getting Chicks - Flicky: Collect 80,000 points' & 'Critique - View all artwork' This is a great buy, although it may make you feel old!!!
