I love to own this, it's Sonic's Ultimate Genesis Collection.

Sega Reveals Huge Genesis Compilation:
A list of features and titles so far revealed for SUGC can be found after the link, courtesy of Sega's official site for the compilation.
Publisher Sega just announced a huge collection of classic Sega Genesis (aka Mega Drive) titles en route to the Xbox 360 and PlayStation 3 in a package dubbed Sonic's Ultimate Genesis Collection.
40 games from the venerable 16-bit system are planned for the collection, though Sega also promises a number of additional downloadable classics and games from the 8-bit Master System as bonus content.
No firm release date has yet been revealed for the $30 SUGC, though the official announcement claims the compilation "is slated to ship to retailers in North America in Spring of 2009."
Sega has released a number of collections over the years -- all of which were missing one or two key titles.
FEATURES:
• THE LARGEST COLLECTION OF CLASSIC SEGA TITLES. All the favorites are here including Sonic The Hedgehog, four titles from the Phantasy Star™ series, as well as three titles from the Streets of Rage™ series, to name a few.
• UNLOCKABLE CONTENT. Unlock arcade games and interviews with the original game developers as you earn Achievements on the Xbox 360® and Trophies on the PLAYSTATION®3.
• ALL TITLES UPGRADED TO HI-DEF. The classic 2D style never looked so good! Each of the titles has been converted to hi-def (720p) and will be a blast to play using the intuitive controls of the Xbox 360® and PLAYSTATION®3 systems.
• MASSIVE MULTIPLAYER OPTIONS. Play these classics together with a friend from the same console at home.
