I like nostalgia, really I do but all these games are so dated, I wouldn't mind if the games were true classics like Scramble, Defender, Pheonix or some classic platform games like Donkey Kong or Super Mario which I know all aren't Sega. The Sonic series are, ok, maybe worth a go but even then you get bored very quickly. If you do buy it here's how it will go, you start off thinking I'll start off with the earliest game, then you play.....for about a minute, then the next earliest......for about another minute, then another and another. Then you think sod this i'll try the latest game and then you play that for about 5 minutes, then the next latest, then the next. Then you play Sonic and have a little bit of fun although still bored and wishing you were playin Battlefield, Uncharted or Assasins Creed. Then you give up, pack the game away and promise yourself you'll never get it out again.
To sum up 'A COMPLETE AND UTTER WASTE OF TIME'
