SEGA Europe has confirmed today via its Twitter account that SEGA 3D Classics Collection will eventually come to Europe. To put a long story short a Twitter user asked SEGA Europe what was happening with the game as it’s due to be released in the United States very soon. SEGA Europe said they’re working on it, but have nothing to share at this moment in time with regards to an actual release date.
@NostalgiaNinja we're working on bringing them to Europe – we don't have a date to share at this time.

Ye
Shame Sega didn’t expand upon their titles and make them as lovable and iconic as Sonic. If they were successful with that they would’ve had an really big chance of blowing Nintendo out of the water.
