Wii u had 60 exclusives in 2015 while the PC had 19, PS4 and 12, and the Xbox One had 3.

There's zero credibility to this video when the creators of it include Rare Replay as an XB1 exclusive, when each game in it can be bought on 360 or the original XBox.
Exclusive is only available on one platform, there are no provisos that allow a game to be exclusive if it's on another platform.

I wouldn't count The Nathan Drake collection or games you can buy on Vita or older Playstation platforms like the ports of PS2 games made for PS4 with the emulation tech Sony's made.
