I just always try to keep in mind that all advertisement/trailers/pre-release statements are 100% marketing optimized platitudes that may or may not be the furthest thing from the truth. Minus points are automatically deducted everytime I hear/read the phrase "we heard/listened to the fans" (seriously, I've never ever had a single such statement go over well, everytime I heard that phrase, things took a turn for the worse, without fail!).

That is then compared with any personal experience with the developers and publisher. That is then interpreted as a basis for the likelyhood of which of their marketing BS is the least inaccurate, upon which I will then decide if whichever I gleamed from that is favourable or not.

So I need to think of a trailer I think misled me?

I'll have to think about it but I suppose I will sticky this in the meantime.

This is your last free sticky though, the next one will cost a dollar.

What was the product in question?: Star Wars the Force Awakens

How did the marketing differ from the release?: Kylo Ren was a huge pussy. Turd nuggets.

Do you think it was right to have marketing that misrepresented the final product?: I couldn't give any less of a fuck.

Did you end up liking the final product regardless? Why?: Yeah, it was cool. Space ships and shit.

Will this make you weary of future advertising?: Fuck advertising. All that shit they spammed before the movies? Ads and shit? Not buying any of that garbage ever. Simply because I had to sit through it.

This is the best idea I could come up with. So don't worry about it.
I suck at coming up with stuff like this 

But Cknarf throwing a shit fit above and answering like that isn't helping much. Rather confirming what you mean.

No problems then:

1. Command and Conquer 4 -  Tiberium Twilight
2. Marketing had stressed the back to the roots mentality, when the final release's game mechanics had incredible little in common with the familiar basics the game series.
3. No. And evidently the ensuing backlash was clear enough when the developer and publisher quickly backtracked on several statements and clarified their vision.
4. No. Not at all. The pre-release demo already culled my desire to buy the game at release and the subsequent informations that came out from several trusted individuals from the playerbase led me to watch a playthrough first, upon whence completion any desire to buy the game was quenched.
5. It has definately. The blacklist clause for "we listened to/heard the fans" is a direct result from that particular experience.

1. Battlefield 4
2. Less the marketing than the assurance of the game working properly (which is an important facet for a MP game). The game did not work properly. Server, client and game crashes were abundant and the game itself riddled with numerous annoying bugs/glitches.
3. The product itself was not misrepresented. All the promised content was available and when the game ran fine, it was what I had hoped it to be. However the game's production was clearly rushed (almost certainly to compete with the other big FPS MP, CoD). Considering it took around two months full of patches to eliminate the most common technical difficulties, the game was far from ready to be released as it was.
4. Yes. As stated, once the worst problems were ironed out and the game performed stable, it was all it was meant to be.
5. Yes. I've followed more recent releases from the same developer to see if other game releases suffer from the same initial technical problems and am still conflicted on whether I'd consider buying a game of their's at launch or wait for a couple patches. I also compare the developer statements regarding patch notes with any given marketing promises.

Right, nothing really comes to mind, so here you go.

1. Gundam SEED OP
2. It has T.M. Revolution.
3. Using T.M. Revolution for bad anime should be banned.
4. Warder and Impulse like it.
5. I will always love T.M. Revolution.

1. Ar Tonelico 2
2. It was marketed as a dating sim first, a game second.
3. Incredibly, it would have benefited the game a lot more had it been advertised on it's strongest points like it's soundtrack.
4. Not the NISA final product as much as the Fan localization, but yes, I enjoyed the game greatly. I would put more into what I liked about it but the last time I did that it turned into a 1000+ word review.
5. I have been weary of advertising for JRPGs for a long time.

1. Destiny
2. It was advertised as a open world, deep lore and story, MMO-FPS mix.
3. No.
4. Somewhat, but if it had more of what was advertised I would have enjoyed it more.
5. I am now weary of all video game advertising.

Wish I could do more than for games.

Please don't start an argument here.
