The Sega Genesis/Mega Drive Mini is shaping up to be a pretty awesome mini console. The system will have 40 built-in games in total, and 10 more have been revealed to bring the total announced games to 30 so far. They're even working in some rare treats, like Mega Man: The Wily Wars, which was previously exclusive to Japan and Europe. 

Here are titles 21-30 of the western Genesis Mini:

• Mega Man: The Wily Wars
• Street Fighter II’: Special Champion Edition
• Sonic Spinball
• Phantasy Star IV
• Beyond Oasis
• Ghouls ‘N Ghosts
• Alex Kidd in the Enchanted Castle
• Golden Axe
• Vectorman
• Wonder Boy in Monster World

Japan's 21-30 looks a little different:

• Ghouls ‘n Ghosts
• Street Fighter II’: Special Champion Edition
• Mega Man: The Wily Wars
• Golden Axe
• The Revenge of Shinobi
• Phantasy Star IV
• Beyond Oasis (The Story of Thor: A Successor of The Light)
• Puzzle & Action: Tant-R
• Party Quiz Mega Q
• Yu Yu Hakusho: Makyou Touitsusen

To sweeten the deal, it's even been confirmed that The Wily Wars runs at 60Hz on the Mini, which is the ideal NTSC experience and superior to the 50Hz PAL version.
