Ubisoft releases some good games, just not enough to make up for their failures with other titles. The team that does Rocksmith released two games and both were polished and didn't have any issues at release, I'd assume that they are working on another installment to release for the holidays this year though, but the core of those games doesn't need to change much, they just have to add in functionality and program different techniques in order to further improve the depth of the songs they can release as DLC. And Rayman has always been really good as far as release games go.
And you forgot Popcap, they ruined them and made PVZ2 into a P2W game hardcore.
