Do you mean something besides difficulty? I already said why difficulty shouldn't be an issue, and even if it became an issue I wouldn't care, the option to take four players and barrel over everything would still be nice to have, and this is the second time they've failed to deliver it.

: and break their promise to deliver the same gameplay as the original.

What are you talking about? No it wouldn't, they could easily still have all of the original gameplay plus the option to have two more players in co-op. I know you mean well and you're happy but you're coming up with excuses for them, these are the kinds of things a marketer would say.

: Online co-op delivers on the promise of a feature that almost made it into the original.

Was four-player co-op also supposed to be in Halo 2? Was it ever planned or intended? I seem to remember that was among the many things were planned (at least in some form) and scrapped.
