I'm going to need a citation on that.

: It's what games have been doing, like forever.

and that

: Half Life 2 ran at 30fps on the original xbox using Havok. If you are telling me
: that a console two generations more senior couldn't do the same at 60,
: then someone is awful at their jobs.

What does that have to do with the above, or Halo 5?

: Also turning down the resolution is not a bad idea at all. MGS4 was 540p and
: it looked great.

It's not about looking good, it's about both players being able to see detail, and about MS being unwilling to compromise on graphics.

: I know perfectly well how programming works.

I doubt that.

: How about this: Quake on the N64 had FOUR PLAYER split screen.
: A 3D game running on crappy hardware.

"Crappy" tells me nothing. It was way ahead of the Genesis you were extolling the virtues of before.

: It's 100% possible on the Xbox One if you plan for it. They CHOSE NOT TO DO IT.

OK so why do you think they chose not to, if not for technical reasons (and possibly also constraints from management)?

: Maybe that's true, but I hear an awful lot that no splitscreen hurt the game significantly.

well of course

: Doom 2 came out a year later. It was still novel. We are 15 years out from
: Halo's launch. It's old news.

As much as I don't like most of the whining about how Halo 5 isn't Halo, it's very different from Halo 1 and really all of the games, except for Halo 4, which it's still pretty different from. Halo 4 was itself pretty different from all the Halo games except Reach.
I mean, the changes aren't things new to gaming as a whole, or to the genre, but to say it's stale when they seem to be going out of their way to change it....
