The problem right now is that the levels seen are not open, it's rendering a ton but the amount of space that actually comprises the actual playground isn't nearly enough to justify the level of sacrifice they took in terms of graphics in SP, if co-op and mp don't look mindblowing, it's understandable, SP should really be wowing people even the first time they see it. There was a massive gap between what something like Q4B was offering in terms of rendering dynamic and self-shadowing as well as lighting that doesn't look pre-baked or flat, as well as reflection-mapping the water and giving it ripples, they've taken steps towards addressing those but in terms of catching up to the likes of Motorstorm and UNCHARTED!!!111!!!
, is it enough? Are we fighting a hundred enemies in sp? Not in the demo. The whole point is not RENDERING a ton, but having that interaction with EVERYTHING in that level.
If you can literally climb up a goliath right then and there and fight INSIDE the goliath, walk on top of the goliath WHILE it's moving, THAT would be impressive. If you can shoot down one of the vehicles in the sky in real-time and it can crash-land on an enemy, THAT would be impressive. What the SP is doing so far is funneling the player through one corridor after another. The co-op levels are more impressive in that you have a large area to play inside and you can go all the way around to flank the enemies. It's like the leviathan fight, if you can actually jump ON the leviathan and fight other chimeras inside it, that would be impressive, right now the E3 demo seemed like just going through a linear level while occasionally shooting it to get it to respond, I hope there's more to both of those scenarios.
