None. Every company can make a bad game, regardless of their pedigree. Nintendo made lots of good games, along with Amiibo Festival. Next Level Games made Luigi's Mansion 2 and some great Mario spinoffs, but are currently making Federation Force. Rare made tons of classics... as well as terrible licensed games in the NES era and mediocre Xbox ones. Sega... oh forget it. Them and Capcom went from great to terrible very quickly.
