Neobr10: Killzone 2 and Motorstorm backfired for Sony, actually. Those CG trailers were very misleading, the final games looked nothing like what they had shown and many people got pissed.
I agree on Motorstorm (although the game does still look great) but you are simply and utterly wrong about Killzone 2 (unless you mean it in a positive sense, which you don't :P). Yes, the E3 2005 trailer was pre-rendered and people did get pissed about it but the final game actually looks *better* than the trailer. I have yet to meet the person who actually played the game and does not think so.
This is the controversial pre-rendered E3 2005 trailer This is the same sequence from the final game Yes the sequence was altered, that view of the sky in the beginning was removed (or rather replaced with another fantastic view), they removed the flight just above the roof tops but most of the stuff you see is either present or can be found at later points in the game in some form. And the "gameplay footage" at the end of the trailer doesn't even get close to the visuals in the final game. Just compare it to the beach scene at ~4:30 in the walkthrough I linked to. Some things look different but the game sure as hell looks better than the trailer.
The only people who can possibly claim that the trailer was misleading after having played the game must not have seen the trailer in a direct comparison. The trailer looks MUCH worse than I remembered it.
And the other game I mentioned was Metal Gear Solid 4, not Motorstorm. And again: the
final game actually looks better than the E3 trailer that blew everyone away.
Neobr10: I'm pretty sure that for many people out there Uncharted 4 is a very good reason to own a PS4. Actually, anything that comes from Naughty Dog is a good reason to own a Sony console. In my opinion Naughty Dog is currently one of the best AAA studios around.
Yeah, sadly I don't share most people's opinion on Naughty Dog. Their games are in my opinion utterly overrated. But I get that other people feel differenty about them. Well, I still don't get why Uncharted is as popular as it is but yeah, I respect that other people enjoy the series.
