I think his point is that Mass Effect, Mass Effect 2 and Dragon Age: Origins also had bugs, but they were not mentioned in any reviews I know of.
I had to restart my first ME playthrough after a corrupt save. Dragon Age: Origins has a few bugs, but none that are gamebreaking. Mass Effect 2 was not so buggy, but you could get stuck in enviroments and that would mena you had to reload you last save.
