I have someone I work with tell me about her unhappiness at why Rockstar allows for cross console change from X360 to PS4, though Bungie didn't/doesn't support the same. I wouldn't think it technically impossible to restrict exclusives/achievements that aren't possible for Xbox players because of Playstation exclusives.
Just exclude/remove them during the transfer, and set some form of restrictions because they don't support cross platform play mostly due to what they say is technical limitations, but mostly would be the perceived notion that newer consoles have better hardware. It's the reason there isn't PC/Console play for most games because PC Hardware is leagues above console hardware. I look at it like the limitations of many Routers to throttle down the WiFi to the oldest/slowest 802.11B/G/N device, and that's why people have dual band Routers now. Another analogy is traffic on a road being restricted by the lead car, that's why slow traffic stays to the right in the USA, or there are passing opportunities with a broken center yellow line.
Thank you for reading my question and any constructive replies.
