Halo MCC, AC Unity or DriveClub. Which was the biggest mess?

[Augen]

Oddly for me AC:U was no where near as buggy as ACIII so seemed okay to me.

Drive Club and Halo suffered from being rushed out 4 months early, debate is if Driveclub's already year long delay make that worse or Halo being a collection of old games makes it worse?
