- Global War: Not just one city or one island, but different areas all around the world (like MW3's campaign, but executed much better). Then, we could have urban AND jungle environments, not have them both crammed into one. And maybe, at the end, you'd return to the Lingshan Islands, and then that's where the game would end. But that'd be too clever. Instead we get the jungle of Lingshan with the streets of New York. Lazy.
- Moar Nanosuits: Okay, so we got Alcatraz, check. What if we threw Pyscho and Nomad in there? I think they might be dead ("You turned them into dead men walking!") but I wouldn't care if they overlooked that and brought them back. Then we could maybe play as all three of them, making the global war execution a bit easier. Or heck, just make up random characters. This would open avenues to co-op, and that'd be awesome.
- Moar Enemies: So in the trailers, I believe we can spot one new Ceph enemy type. Cool. Why are the rest the same exact ones? Transitioning from Crysis 1 (where everything looked like a squid) to Crysis 2 (where everything looked all metallic and cool), why isn't the same with Crysis 3? Why don't we see a new array of enemies. I mean, it's been YEARS, right? And C.E.L.L. again? Didn't we already do all that in Crysis 2? Whatever. Might as well bring in some North Koreans, too. They already have the jungle.
- Moar functions: Alright, Stealth, "Power", Armor, yadayada. Crysis 2 added Nanovision, which was garbage. Why can't we get something new, something possibly big? Like a jetpack? Didn't Nomad have thrusters on his 1.0 suit? (That never made sense to me.) Maybe that'd nullify jumping, but then maybe make jetpacks loud and jumping more stealthy, or make the jetpacks more horizontal. Just something significant, at least.
- Moar Weapons: One of the major issues with Crysis is that it has a severe lack of weapons. Which is fine, so long as they're all balanced well (i.e. Halo), but in Crysis 2, they weren't. They were horribly unbalanced (Jackal anyone?). But from what can be gathered from the trailers, a few new weapons are around, and one is an alien rocket launcher. More alien weapons? I hope so, but I'm not counting on it.
- Moar vehicles: Take the Crysis 1 approach, where you could venture from Toyotas to tanks. Although I doubt we'll see really any vehicle action in Crysis 3. There were only two instances with vehicles in Crysis 2, and those were on streets. Put a bunch of vegetation in front of those streets... where do you drive?
- Moar original multiplayer: Crysis 2 was a cookie-cutter Call of Duty deal, but with even worse balance (LTAG anyone?). One may say that it's hard to be original when there's not much else to do, but look at how other games are reinventing their multiplayer. Halo 4 looks really fresh and beautiful, and I hear Black Ops 2 will have a whole new class setup. For Call of Duty, that's saying something.
This is all I can think of right now, but I hope that some of these concerns of mine will be put to rest when I pick up the game. This is just what I had hoped for when I beat Crysis 2, but I see that that's no longer a reality.
I personally blame EA. This is the same situation we saw with Mass Effect 2. Developer makes first game, it's okay but not very big. EA buys them, they make second game. Second game is good, and it gets big. Then EA tells them to release the third game within two years, and that's where it all falls apart.
