Yep, the collection has finally started production. And from what crimson said, this screen shot is nothing compared to the finished version. Although I haven't talked much about the collection so allow me to explain a bit.

The collection will have all the versions of the original sonic.exe such as:

V1,V2,V3,V4,V5,V6 and V7.

But Even a few other tag-alongs too!
Such as The original remaster made by Sonic's gaming Hub and A Sonic Mania remaster version of it!

Maybe a few special entries too.

But during the selection of them all, there will be info about the games and their back-stories too.

But if everything goes as planned I believe that the collection should be done first before the "TYoCT" edition releases. So keep an Eye out for further Updates!
