SEGA has announced SEGA Mega Drive Classics — orif you're from North America — a compilation of more than 50 SEGA Mega Drive/Genesis games. The official announcement comes after the company accidentally spoiled the news of the collection last night by posting a trailer, which was promptly deleted. Oops.

Although we don't yet have the full list of games in the package, SEGA promises "arcade action, shooters, beat’m ups, puzzlers, old favorites and hidden gems." Of course, you can already get a glimpse of some of the guaranteed inclusions in the above trailer, even if some of them are obvious (of coursewill be there). The collection boasts "online multiplayer, achievements, mirror modes, rewind and save states," although the specific details for each game included have not yet been released.If you're wondering howwill stack up to SEGA Mega Drive Ultimate Collection from the Xbox 360, the current gen version advertises "more than 50" games while last gen's advertised "more than 40."
