Xbox' fall lineup is fine, but it can only be crowded with some unannounced titles in my eyes.
Halo is fine, Forza is fine, TR is fine, but overall it's a bit meh.
I recognize that Forza is a good series, but if you're not into racing simulators like me, it kind of means little, although diversity is always great.
TR was such a meh game, that I'm not super stoked about RoTR. Even if it's a good game, it's kind a just a bleak and brown Uncharted.
Halo 5 is a seller no matter what anyone says, but I personally am somewhat turned off by it since it's reveal, and since the bad taste Halo 4 left in my mouth. I'm definitely curious about it, but it's just another game to me now, not "The next Halo".
Ultimately, Halo/Forza(/Fable) is exactly what is expected of MS, nothing more, nothing less. This is the time in the generation where new IPs help shape the consoles identity. I don't know if I've just gotten greedy, but I don't feel like Xbox One have spawned any new franchises yet. Rather they have just been making mediocre iterations of previous franchises:
Crimson Dragoon, Dead Rising 3, Forza 5, Spartan Assault, KSR, and so forth.
And while Sunset Overdrive, Project Spark, Forza H2 and now Ori were pretty good, It just doesn't feel like it breathes enough fresh air into the ecosystem.
Phantom Dust, Scalebound, Crackdown, Quantum Break and Ori were the games I was looking forward to from last E3. Ori is here, but all the others are 2016 now, it seems. If they can all even make that.
Perhaps I don't have a right to complain since I don't really own an Xbox One yet, but I have been with Xbox since the OG came out, but now I just don't see a good enough reason to jump ship yet.
