So, general points:
-If Uncharted counts, then Gears of War does also (possibly to its detriment, since by Gears 4, while I enjoyed the game, the formula's starting to get stale).
-For Doom, Doom 3 and its related spinoffs are a clear break in consistency, down to tone, to gameplay, to lore. I say this as someone for whom Doom 3 is their favourite entry in the series, but I can understand why it's the black sheep in the series.
-Nintendo's IPs are relatively consistant, but of the ones CoCage listed, Donkey Kong kind of went off the rails after DK64 prior to Retro Studios. As for Metroid, I'm not sure if I'd argue it's consistent. Even leaving aside stuff like Other M and Federation Force, there's a pretty clear divide between 2D and 3D Metroid, even more so than Zelda.
