I am little disappointed that the key which comes with the game won't get registered on steam, basically meaning that it is a non-steam version. It plays just fine from the disc but it would be better if it were the Steam version. The game needs a disc every time you launch the game which is an another little disappointment. So that will conclude one star off my review score.Games included on the disc are nothing but pure 16-bit of awesomeness. If you missed the chance of enjoying Sega games back in 90s then your wish has just come true. Just grab this copy and dive into the 90s awesome video game era.
