Ubisoft is definitely in the top 5 when you add everything about them up: Some of the worst, if not the worst anti consumer practices in the west, absolute slop that they have perfected as an art form, contributing to every game being a service and open world, ruining some of the best IPs in the business(Rayman, Rainbow Six, Prince of Persia, Splinter Cell, even Assassin's Creed wasn't complete dogshit at one point), and having some of the most insufferable developers and PR in gaming. When you take each on its own, they're not that bad, but when you add it together...Definitely in the top five, not anywhere close to number 1 however.
