Quote from Pericolos0more mods have done this you know... professional companies do it too...
So it's okay then?
Valve got bitched at for having most of the E3 footage and other promotional content not in their actual game (and also when they lied about a scene that had was supposed to have no scripted sequences)
CoD2 got called out for having prerendered cgi in it's ad, that didn't depict what the game actually looked like.
Well in their "pretend to be a game studio" setup, they got one thing right: lie like one.
