This game shows that old games are still fun.
Anyhow, the games run smoothly. The only problems that any of them have are problems that the Genesis versions had, which isn't much. In addition, there is also several Sega Game Gear Sonic game in this package as well. The one thing I don't get is why yhe are non-Sonic games that can be unlocked.
If you used to have a Sega Genesis and loved the Sonic games, then I suggest that you get this. Even if you never had a Genesis, but have played more recent 3D Sonic games, then I still suggest that you get this, as the old 2D games are better than the 3D ones.
Have fun.
