75-80% on PS4 and 20-25% on X1.

Hard to believe how many people actually thing it will sell at least 30% on XB1 considering the gap and the difference in demographic.

A more appropriate question would have been "What Final Fantasy fans are actually making XB1 their primary system?" It's more of a dudebro system, not a NEEERRRRRRRRRRRRD system.

If you have both consoles - you may want to go Xbox with this title...

99% on PS4. With a 1% margin of error.

If the PS4 overheats, you have to wonder why they didn't run it on an Xbox One. Let's keep in mind that the PS4 is stronger than the Xbox One when running those scenerios in your head.

That said, this wasn't the Gold version of the game, and this PS4 could have likely just been old (they collect dust rather quickly and need yearly cleanings).

70 to 30 percent. FFXV hardly seems like a niche game and I am sure the ratio will resemble that of most open world RPGs...

In other words, no worse than F4, SSE or the Witcher III...

Power and ventilation are not related and even if they were, it'd actually be worse in the console with less ventilation. 

And if you have experience with a PS4, you'd know the entire backside is a large vent. Grats.

85.5% vs 14.5%

They might aswell make the future FF exclusive. Crazy ratio incoming.
