We get to see not only Sonic's birthday, but also the inclusion of Amy in Sonic Origins soon!
We can finally play as Amy in Sonics 1, CD, 2, & 3K!
"but we already have amy in sonic 3 it's nothing special"
Fangames don't count. I'm talking official inclusions, so that little extra character mod of her for Angel Island Revisited isn't an official inclusion.
I wish I had something to play Sonic Origins on now.
