Batman Arkham Knight
"Warner Bros. knew for months that the PC version of Batman: Arkham Knight was broken, yet still chose to release it. One of their anonymous sources was quoted saying: I will say that it’s pretty rich for WB to act like they had no idea the game was in such a horrible state, It’s been like this for months and all the problems we see now were the exact same, unchanged, almost a year ago. Two sources spoke with Kotaku over the past week to explain the release of the broken PC version of Arkham Knight. Both of them stated that Warner Bros. knew that there were many issues facing Arkham Knight on PC but still chose to ship the game, believeing that it was good enough."

Assassin's Creed Unity
"The various versions of Unity had hundreds of bugs, some nearly game-breaking, when the game came out on Nov. 11.... Issues at launch included protagonist Arno Dorian falling through the ground and getting stuck in hay carts, problems with the in-game currencies, and characters with missing faces ... but not eyes."

Mighty No. 9
"some users have said that Mighty No. 9's Wii U version is causing freezes on that console, and that the game's lone downloadable content extension (an extra villain) "apparently breaks the game."
Mighty No. 9 had a rough launch day
"Mighty No. 9 was a broken mess when it came out and the developer tried to fix it but they really didn’t. It still had a lot of issues and it looks like Microsoft took it upon themselves after the game was abandoned by the team. Today, Microsoft released a patch for Mighty No. 9 which the Xbox Team created themselves."

Aliens: Colonial Marines
"Five years after the release of Aliens: Colonial Marines, a modder has discovered that a simple typo in the enemy A.I. code had a major, negative impact on gameplay... Sadly, the Aliens: Colonial Marines that was released after many years of delays for PlayStation 3, Xbox 360 and PC wasn’t the title promised in those initial previews. In fact, it was an incredibly mediocre shooter littered with bugs, glitches and terrible enemy A.I. The xenomorphs, in particular, were far from the intelligent, lightning fast enemies from the movies, often getting caught on scenery and moving in sluggish, jerky steps that made them easy prey for Pulse Rifle fire... Some fans have spent years modding the game to improve the A.I, lighting effects and other glitches, but now a modder named James Dickinson (via PCGamesN) has discovered the erratic xenomorph A.I. may have been caused by a single typo in their coding. Dickinson discovered that by looking in Aliens: Colonial Marines games config file, that a piece of code reading 'AttachPawnToTeather' really should have been spelt 'AttachPawnToTether.' Since this has been discovered, many players have found that correcting the code makes a big impact on how the Aliens respond. They’re much more aggressive, and actively hunt the player and try to flank and ambush them."
