Ubisoft gets a lot of flak for AC: Unity and rightfully so. The game was obviously not completely ready for release. However, it was fixed quite quickly and I had absolutely zero problems completing the game in many hours of the campaign and co-op. Never saw any of the glitches that were reported and the framerate was relatively stable. I bought it day one but waited about a week and half to play while I completed AC: Rogue. It seems a lot of people think this game was either broken for quite some time or is still broken today and that is not the case.
The other two I have not played so I cannot speak to their issues personally. From what is being widely reported Halo MCC is still not fixed so I suppose that would be the choice.
Hopefully we talk less about broken games this year. But with publishers continuing to push developers to make a certain release date it seems that releasing broken games is an issue that will persist for the foreseeable future.
