Fun and Games: looks more warmer Spaced Out: looks more cooler
Fun and Games: glitter Spaced Out: sheen
Fun and Games: as you can see here "Fun and Games: has more of a "orange" glitter cast to it. Spaced Out: here "Spaced out" has an opalescent duo chrome sheen to it.
Overall: In person I can see how the two looks very much similar, but as you can see here no MAC product is alike. When I went to pick this blush up ...one of the MA loved my blush (I was wearing "Spaced Out").
