10 'Next Big Thing' Video Games That Failed Miserably

4. Assassin's Creed Unity

Do you remember seeing AC Unity for the first time?

Even back in 2013, we weren't buying it. We weren't buying all the talking head 'behind the scenes' featurettes espousing the notion that Ubi had 'built the new engine from scratch', and that it was going to be 'a brand new Assassin's Creed'.

It just.wasn't.happening.

Come launch, that above facial bug was everywhere. Ubisoft were forced to change their company slogan of "The next generation starts here" (something they were actually running with for months prior) as the sheer scale of Unity's problems were unprecedented for a triple-A release.

Frame rates chugged, characters' faces didn't load in or random wandered into cutscenes where they didn't belong - the Xbox One version in particular required a 150GB 'patch' so big it replaced the entire game.

Think about that: Unity's launch day code was so broken, Ubi had to swap the whole thing out for people to even play.

Madness.
