While this looks absolutely fantastic (cloth physics, lighting and texture work is all best in class) and I know it's a trailer so they have to show something exiting. I am starting to get a bit worried they are going to far towards the the CoD roller-coaster school of design, wall to wall highly scripted action is not what I want from metro, I want the atmospheric tension of creeping around in the dark making mad dashes out on the surface etc with precious little ammunition, and groaning whenever I lose a throwing knife. And very little of that is shown in these videos, I hope they do some Dues Ex: HR or Far Cry 3 style multiple run though demo's that show multiple paths and less scripted combat sessions.
I agree. It looks stunning but it also looks incredibly scripted and linear. I'm about half way through Metro 2033 right now (Chapter 4) and I like that even though the path to completion is linear, there's a lot of psychological twiddling that goes on between point a and point b. You've got to stay quiet, you've got to conserve ammo, you've got to make sure you have an escape route planned, you've got to be ready for unexpected attacks, and you've got to have the nards to explore for resources. What they've shown doesn't give me the same vibe the first game is giving me. But I'll wait until we see more as I think they're mainly putting out these high-octane scripted sequences to entice that CoD crowd.
Don't worry. I've been following 4A on twitter and their response about showing the action sequences is reasonable. They wanted to show off the improved gunplay, A.I and stealth. Rest assured, the survival-horror elements are still there. I have faith in these guys.
Also, In my opinion, I find it a bad idea to show off a horror game in any crowded gaming convention like E3. These types of games are better played alone without being surronded by a group of people and spoiled by watching early footage. Hell, most previews of Silent Hill Downpour were a freakin' disaster just because the geniuses at Konami thought it was a great idea to show it off in its early stages in an open convention. I'm still getting the game but you get my point.
