teaser trailers. they basically do nothing beyond confirm that something exists, and far too often *cough duke nukem cough* they don't even do that. usually a camera pan of a character or a live action event that really doesn't tell you anything about the game or movie. so if you judge it and aren't in the norm, you'll inevitable come across the jackass that says "dude. it's just a teaser, wait and see." 
 
now that pisses me off. the whole point of a trailer of any kind is to decide whether or not you like it, their entire point is for you to judge them! if they're willing to spend that much time and effort on a teaser, god knows how much they spent on the actual GAME. not only that, but in the case of a a trailer with gameplay and plot details, that should be enough to tell you what to expect in the game. in the case of ratchet and clank: all 4 one (god i fucking hate that title) all i saw was a shitty ass party game that lacked the iconic weapons of the series. 
 
little side rant here, why the fuck would you play a shooter if you don't like the gun play? there were like 4 guys on my reaction to ratchet and clank party (i refuse to call it ratchet and clank 7) that said they didn't like the gun play on R&C, a shooter! go to kongregate there are literally thousands of free paltformers! hell buy a wii the only good games are platformers! well i guess that's not true but you get my point. 
 
anyway...back on track. so yeah i guess that's it. that's how i feel on teaser trailers. huh. i feel angry now, i'm gonna go play infamous, something that makes me happy. maybe i'll go watch an uwe boll movie and piss myself laughing, that's always fun.

IT'S A FUCKING AD

If any debut trailer has more than a logo then they've already gone above and beyond my expectations.

I'm ok with teaser trailers as they usually do a good job of teasing people into want more, which is the point.
 
I would like to point out the Brink teaser trailer. It gave almost NO clue as to what Brink was like. Most of the feelings from the teaser did not make me think it was a class based mulitplayer shooter.

it's amazing how angry people get on another person's opinion.
