I'm pretty torn about this.
I think the world would quickly see that H3 hasn't aged particularly well.
The AR, the magnum (and all of the dual wield able weapons) the BR sucked. As did equipment.
But I'd kill for the ability to play oddball, or the "real" Assualt gametype again.
Also, h3 had the best customs... And we'd likely get a customs browser!!!
Also, Bring on the brute chopper.
