I am starting this thread as a place to throw all the bullshots you can think of over the years, and likely ones that we're seeing more recently (and the inevitable bullshots we will get @ E3).
Bullshots are pics/videos of games that are not what the final product will be like, usually intentionally run/rendered on high end PCs due to wanting to make the product super exciting or hype-worthy. Sometimes it can be also attributable to incompetence.
This isn't a console-war thread either, pretty much platform has seen bullshots over the years, and they're VERY common with new console launches timeframes.
A famous past example was Killzone 2 2005 Target Render trailer. While the end results were admirable in many ways, we never saw the full quality of that 2005 trailer achieved in the end product.
More recently you have the 'Downgradaton' with Watch Dogs from 2012. Another target render with quality set unreasonably high, and the end product falling short of that even on $4,000 PC rigs. And of course, Forza, Alien : Colonial Marines, Dark Souls 2, so on and so forth.
I can definitely guarantee that we're not through with Bullshots and downgrades, it's just the nature of the industry these days. What's next, and what are some others you've noticed.
I'm laying a huge bet that the Quantum Break footage is basically BS (in terms of what players will actually get on XB1 consoles). A dead giveaway in many cases is the use of language. Whenever you hear phrases like 'in engine', or 'on X console hardware', it's sneaky ways of covering their butts. 'X console hardware' can mean a high end PC dev kit that happens to have the console branding for the dev purposes. And 'in engine', great, another meaningless term entirely. 'In-engine' on a $5,000+ PC perhaps. I have little doubt that at least another example lies somewhere in the Sony lineup as well. Like I said, it's annoyingly common.
