That's still too much for my liking. I'd prefer one trailer only. I miss the glory days on ps1 when we developed our opinion of the game the day we played it, not 6 months/ a year before. I'm on a media blackout (then why are you in the thread etc) and I still catch glimpses of the environment here and there, wish I could avoid that.
For all the shit the Uncharted 3 marketing campaign got (for showing too much of the setpieces), it kind of worked really well, considering it is a 10+ million seller, much more than its previous entries.
