Excellent compilation of the best games of megadrive. I am a fan of Sonic and Street of Rage, it was happy to find these old games on the ps3. By cons there are considerable differences between the games, especially at the level of the soundtrack and graphics. Games such as E-swat cotoient Sonic, Ristar, ecco the dolphin or Vectorman (one of the games that has the best graphics). By cons where past Flink, Rocket Knight ??? Sonic otherwise have absolutely no aged: as beautiful visually and musically on an HD TV. In addition there are lots of unlockables, including Altered Beast arcade version (thousand times more beautiful than the non-released version of megadrive) and trophies are incredibly easy to unlock (except that of Dr. Robotnik (I leave you the joy of you rub y)) Here. I recommend this unexpected compilation everyone Good game
