There isn't much to say here. Since we're looking at games that I can leave you blindfolded and you can get pretty far without any help, you might not want to buy it, but you should be alerted that there are 4 games, but you are able to play 2 of the same games as knuckles, so that might interest you. In addition to that there is the artwork (Of sonic!) that you can look at. If you've played these games before, there isn't anything new to do, but if you haven't then you should see what you're missing. I must warn you that the frame rate can be slower than you would want it to be sometimes. There are also some parts of the game(s) where you need to rely on luck.
