Theater Mode:
Not everyone Has a Capture card and not everyone records every single game they play, Also if you do theater mode, have it so it records off of each players view not the hosts view, like Halo 3's not Black ops to help with lag.
Dedicated servers.
Don't know what the specs are for the next consoles but they are most likely going to allow 24+ players on dedicated servers.
Vehicles in multiplayer.
I hears about a mode called power surge or something in Crysis 1 which sounds like a Rush/conquesty Halo gametype, sound Epic and with 24+ players vehicles and big maps will be great.
Ship the game as a Final build not an Alpha build.
I don't think anyone will disagree with this, unless you work at Crytek then you svck.
A horde sort mode.
Horde would of worked incredibly well in this game, it has that feel to it, 6 players against waves of Ceph would of felt great, everything else is design Ideas that are up to Crytek to make their gametype Unique.
If these things happened I would be satisfied with Crysis 3 considering it lives up to its core gameplay in C2.
See ya next time.
