Can someone tell me what exactly is this copy?

[8-bit-dreams]

just confused. I got it along with some other valuable sealed stuff so i'm assuming its a part of a collection but don't know what exactly it is. I'm assuming it is a demo copy as it is written, but, for what? and what does the localize sticker means? Thanks
