We went about this all wrong Val.
Steam.
Steam is essentially a platform that's BC with "last gen" PC games. The majority of XBox360 games just so happened to be on Steam. Steam also just so happens to keep player count numbers for a multitude of games. Surely, if last gen 360 games were so important, we'd see a significant amount of players, playing games from 2007, or 2009 or whenever.
What do you think Steam tells us though?
NO ONE GIVES A s*** ABOUT OLD GAMES THAT THEY'VE ALREADY BEATEN!
Case closed. Bring on the new s***.
You do realize that your system of choice is doing the same thing, right? only difference is they are making you pay for them, again. What do you think remasters are? not to mention that whole' rent last-gen games' service they do.
MS brought BC to Xbox One in order to gain new consumers. BC isn't really meant for those with an X1--although they can certainly benefit. It is meant for those who have yet to move to X1 from 360, and those who never owned an Xbox 360.
