Good franchises that fell off a cliff in the succeeding generation

[Leynos]

Some of you misunderstand. This is only about the generation directly following the previous one. So N64 to 360 does not count. N64 to PS2 would count. Xbox or PS2 to 360 and PS3 would count 7th gen to 8th gen. Not 5th gen to 7th gen or 4th and 5th then to 6 and 7. Sorry if that was not more clear.
