One of the most pretentious games i ever played is The Witcher 2 (and in a somewhat lesser way the original too)...
It tries so hard to be an "adult" game, with lots of sex, nudity, violence and a macho protagonist, but it truly is targeted to teens at best... It is totally unrealistic for true adults, and i don't mean the fantasy setting...
And it is not only the fake matureness of the game, it also tries to present a false picture of gameplay depth, but it is a truly shallow game. Quite boring battles, NPCs that don't really matter, lore that doesn't really matter, nothing to do except going forward the plot...
And don't let me start on its laughable plot...
