Forza 5? Forza Horizon 2? Titanfall? Halo MCC? Killer Instinct? Sunset Overdrive? Have you been under a rock for the past year? There's only one obvious fanboy in this thread.
Forza was half a game with tons of micro-transactions. Has a 5.7 User score on metacritic, because it's an incredibly polarizing title. Also niche sim-racer category. Titanfall wasn't exclusive, in that it released on PC as well, and ran quite a bit better on most mid-range rigs.... Killer Instinct and Sunset Overdrive were mediocre titles, releasing to an overall meh. Killer Instinct also having the troublesome micro-transactions, while having a much smaller competitive following than some of the other fighters released recently.
Xbox One players have been mostly playing third party multi-platform stuff, like Dying Light... and it's not a bad platform for that, actually, despite being a little weaker than the PS4. At $350, it's an inexpensive way to get into playing these multiplatform games. This year though, there's some stuff in the pipe that might change the situation, where Xbox might actually have some strong exclusives. Halo Guardians, Quantum Break, and Fable Legends, all seem like they have the potential to be heavy hitters. We'll see, hopefully lessons were learned from MCC.
Edit: Ah yeah, and there's the Windows 10 streaming thing. That looks cool.
