We would have had a higher cost at release had they added BC. The right choice was made, we continue to get a constant stream of remade games. If BC was a thing we wpouldn't have SoTC, crash and spyro reignited or perhaps half of the rest. We'd still be in the age of "HD" ports. Nuff said.
I wasn't talking about the past though, this is not a "what if", rather a suggestion for the future.
