It's a great game, but the Master System was not popular so people couldn't even put their eyes into it.
Gladly Brazil was the place where the Master System got a proper treatment and reached a good public, so I could cross my way with it.




SO GOOD!

I might be mistaken but aren't the GameGear Sonics essentially the Master System ones?
