By now, we're all depressingly familiar with the hype that publishers have managed to build for video games that subsequently fail to deliver.
We've known for a long time never to trust titles that are marketed on pre-rendered cinematics alone, and more recently have learned not to even trust gameplay trailers showcased at events such as E3.
Heavily scripted "gameplay" sequences for games such as Assassin's Creed: Unity and Rainbow Six: Siege have taught us that Ubisoft and plenty of other companies are not above outright lying about the content of their future titles, and what we're eventually sold can just be embarrassing.
However, this isn't always the case. Sometimes, a game comes along to very little fanfare or amongst intense skepticism and... well, it's good. Really good, in fact.
Sometimes a developer has had a bad run of titles, or a dramatic shift from established formulas has made a fanbase worry about an upcoming sequel, but those designers programmers and testers manage to pull it out the bag and deliver a hit that gives us further hope for the industry.
