The Digital Version of Sonic Generations is on sale for $19.99 on the 3DS eShop till 6-6-2016

It's 33% off

Generations for 3DS is actually good but it's not worth the normal $30 price tag, so if you've ever been interested in it this would be a good opportunity to pick it up. It uses completely different zones than the console version (Water Palace from Sonic Rush and Emerald Coast from Sonic Adventure are some) both modern and classic sonic stages are side scrolling. Don't be expecting massive amounts of content but it's still really good, i'm honestly really glad i own it but i also got it for $15 new through a buy 1 get 1 half off promotion at Toys R Us
