If they were available (digitally) for all of your consoles? Not sure how it would work, whether it's a developer/host registration that would allow for an account the item(s) are registered to be available universally for all consoles where those particular games are available, or if you would get codes for the items (which would be easily exploitable).
Just as a general question though...would it be worth it if they jacked up the general video game price by $20 if it were available for all of your consoles? Personally, I would do it depending on the time of release. If I could wait for sales and get them cheaper separately, I would. But if I want say...Battlefield 4 for Xbox 360, Xbox One, PC, and Playstation 4 to play with my various friend groups...I'd be flat-out broke between all of my consoles and games.
Nowadays I buy all of my games for PC, but I still have friend groups in other consoles. The downgrades don't exactly constitute extra spending...so I was curious how others feel about this who face a similar situation.
