For games with emphasis on story, plot etc then yeah a CG trailer is a great way to tease that. For games where story doesn't play a strong role I'm completely over CG trailers, for announcement trailers I guess they're ok.

i dont like CGI trailers as announcement trailers. show us footage of the game when announcing it. i like CGI trailers when they are done for marketing purposes right before launch, like the Witcher 3 monsters trailers or the witcher 2 Assassins of kings trailer.

CGI trailers are nice to watch, but they don't influence whether I want to buy a particular game or not. That's what real gameplay demos are for.

I think its a shame to feel thé nées to fill thé conférence with CGI trailers, like thé last conférence of Microsoft, was really bad, full cgi

I find the effort well spent, especially if the trailer never makes it into the game.

E3 should have a rule prohibiting new game announcements without in game assets/gameplay footage.

The MS conference last year felt weak despite many announcements, because they were all just CGI.

Pointless. Especially when there on a TV advert and show zero game play
That grips me that does.

It's tempting to say a gameplay trailer is better than CGI, but any kind of trailer can be deceptive. Remember the FF XIII gameplay trailers? Yeah, that looked way more interactive than the game actually turned out to be. And let's not forget Aliens: Colonial Marines, either.

Announcing and promoting a game early in production is just a difficult thing to do. A CGI trailer is fine for it (and easy to put together) so long as the team knows at that point what the game will probably be able to deliver on.

I don't like them at all. If they show them then they should mention it in the trailer or at least be realistic and make them look like the final product.

I don't like them.

Sure, they make their job of impressing us, but that effect only lasts a couple of days leaving only questions and doubts. A gameplay trailer maybe doesn't have that big impact the first time you see it, but the impression it makes lasts longer and tells a lot more about the game, creating (in my opinion) more hype.
