Actually I was prepared to go on a 5000+ characters rant about how disappointed I am with the one game that had tipped the scales in favor of buying an Xbox One rather than a PS4. But I'll make it short: In my opinion, "Halo 5: Guardians" is an absolute disgrace to what has been, since the very first game, my favorite FPS franchise. Or more accurately, my favorite gaming franchise overall. It's got more in comnmon with "Serious Sam" than any of its predecessors. And its technical shortcomings are so stupefying (in other words: this game is unbelievably ugly), I wonder how this could ever have passed QA...
Just to mention this: Since I got "Halo 5" one week ahead of the official streetdate, the 9GB (!) day one patch has not been incorporated yet. I have to play it strictly offline, otherwise the game won't start.
