The only one that springs to mind right now is Resident Evil 4, I guess? That was a pretty drastic shift from where the series was in 1-CV, in terms of perspective and tone and what was added, and now it seems like the series is undergoing similarly dramatic shifts with RE7 and REmake 2. The new God of War also springs to mind as a dramatic shift, although that one seems like less of a dramatic shift. I have a hard time pinning down game genres with conventional terminology (like CoD shares the FPS genre with Portal technically) so this is partly a call for more precise genre definitions.
