in 30+ years I've learned that Nintendo and Sony will always be in my home. Nintendo brings the exclusives and innovations, Sony brings the multiplats and also a bunch of exclusives. Xbox at its best can only give me a handful of exclusives that I Generally don't care about (Shooters and racers aren't really my thing) or are on PC anyway, and while they make an effort to be more powerful than the competition, I've never cared about graphics or performance over unique experiences, good storytelling, and fun gameplay.
I went all in on all three consoles this gen (Four, since Nintendo tried twice), and the only ones that got any play time out of me were the PS4 and Switch. WiiU got a lot of attention due to the Virtual Console and a handful of games (That I now have on Switch), but I have an emulator on my phone now so I don't need it. I have an Xbox One, but I've literally spent more time downloading and installing firmware on it than I have spent playing games on it. In fact, in the 5 years I've had it, I've only purchased seven games. Of those seven games, the only one I've really put any time into was titanFall...and I have the sequel on PS4 now so...
MY point is, I genuinely don't understand why people go for Xbox. The power difference is insignificant (And was actually lesser at the beginning of the generation),the exclusives are on PC, and what 'exclusives' it has are pretty bland and generic. Halo is pretty meh, Forza is a great entry in a genre I personally find boring, and while I do enjoy Gears of War I think it's also pretty bland and generic. Microsft keeps buying developers to foster faith, but have they done anything with any of them? Last I checked, Rare is still making terrible games and haven't done anything good since coming to Xbox, and I'll never forgive Microsoft for that.
For as long as I live and as long as I have a soul, I'll stick to Nintendo and Sony. It seems to be the safest bet. Nintendo exclusives are the best, their consoles usually have something that make them stand out (motion control, touch control, portability, versatility), I don't care that the power is less than the competition, and lately they've been absolutely KILLING it with indie support and lowkey third party support. I've got over 100 games on my Switch and it's probably my most-played console. Sony's exclusives are also pretty damn good, just a step below Nintendo's. and unlike Microsoft and even Nintendo, they reinvent and update and create new IP a lot more often. I mean, we recently got Horizon: Zero dawn, one of the best and most interesting new IP Exclusives of the last decade!
I'll take Mario, Uncharted, Ratchet and Clank, Bloodborne, Spider-Man, Horizon: Zero Dawn, God of War, Zelda, Smash Bros, Mario Kart and various others over the holy trinity of Halo, Forza, and Gears.
