A scripted sequence can't beat throwing a grenade on an oncoming jeep's front wheels only for it to topple over and fly above you... Or detonating a set of C4 charges as a rushing tank moves over them only for its now detached turret to fly off and kill you before you can celebrate your victory (this just happened to me, lol, got tired of C2 after finishing it so I'm playing C1)... Or rushing for cover from a chopper only for its missiles to destroy everything around you like it was made of cardboard... Etc... Moments like that bridge might as well have been pre-rendered cut scenes in Crysis 2, being unable to move and having an obnoxious "press F to look" so that you don't miss it, lol... There are many such scripted moments in Crysis too, like the ship bombing and then sinking near the start of the game. Although most allow you to move still.
As for the suit powers, they're only really "better" from a story perspective. In gameplay terms, it's just a very different style of play. I do personally prefer them in 2, and would like to play a Crysis mod that gives us Nanosuit 2, but that's just me. It's still just different gameplay that some may like better and others not.
Making an Ikaruga sequel where the ship is "upgraded" into purple and can destroy any enemy and make chains with any enemies and absorb any bullets rather than require switching between the red and blue modes wouldn't mean it's a "better, streamlined" gameplay, it'd just be a whole different game really.
And how is the lighting "a full generational leap" when it's still a DX9 engine running on the same and in some cases worse hardware? Hyperbole much? I can only agree that many things look more polished in Crysis 2, as they should. Although it has its fair share of issues too, like rushing jeeps hitting soldiers and not killing them but just pushing them over still standing like nothing happened. Of course with how scripted the game is such things don't happen often outside fully scripted events that work as intended.
And no I'm not saying that Crysis didn't have issues but you'd think with how much more restricted many things are in 2, from environment design to gameplay possibilities, they could have solved many rather than make them even more apparent (as close combat is more common now).
