Sega Genesis
Sega sold 30.75 million Genesis units worldwide. Of these, 3.58 million were sold in Japan, and sales in Europe and the U.S. are roughly estimated at 8 million and 18–18.5 million as of June 1997 (at which time Sega was no longer manufacturing the system) respectively. In 1998, Sega licensed the Genesis to Majesco Entertainment in North America so it could re-release the console. Majesco began reselling millions of formerly unsold cartridges at a budget price, together with 150,000 units of the second model of the Genesis. It released the Sega Genesis 3, projecting to sell 1.5 million units of the console by the end of 1998. An estimated 3 million Genesis units were sold by Tec Toy in Brazil.
Sonic's Ultimate Genesis Collection
Sonic's Ultimate Genesis Collection (Sega Mega Drive Ultimate Collection in PAL regions) is a compilation of video games developed by Backbone Entertainment and published by Sega for PlayStation 3 and Xbox 360. The compilation features 48 Sega games (49 counting two versions of "Altered Beast") which were previously released for the Sega Genesis (including most of the "Sonic the Hedgehog" titles released for the system), arcades and the Master System. It is the sequel to the "Sega Genesis Collection" released previously for the PlayStation 2 and PlayStation Portable, however it is similar to that compilation because it contains 16 (in NTSC regions) more games (including unlockable extras).
