A bit complex in my case. I grew up as a PS gamer. I've loved Sony my whole life and only recently have I really made Nintendo my primary gaming experience. Even still, I consider Playstation to be a console I love, I just don't give it quite as much attention, I guess.
The only one I've never felt anything for is Xbox. I mean, I've played it plenty of times but I never felt like it was too particularly different from what I already had. There are some games like SO, Scalebound and Quantum Break that have my interest but I'd consider a PS4 long before XB1 regardless.
