I like how I showed that they used distinctly similar things and you then tried to twist them into generic enough ideas to apply to something else.
Aside from the outlier of Simon's Quest (and to the best of my knowledge):
They do not have specific new weapons/abilities that are found in laid out story locations for the purpose of unlocking the main story route.
They have alternate paths but they do not allow you to revisit previous levels with items gained further in to open those up.
None of them have an experience points system and while they have weapon upgrades they are not purchased and can be taken away.
None of them allow you to upgrade your lifebar.
You feel LoS is more of what you envision a Castlevania game to be than SOTN. Cool. LoS is not, however, any less of the same genre than SOTN.
