Good scoring everyone.
Reckon Rondo and Bloodlines were a little underrated here (and in general).
Aria and Dawn of Sorrow probs would have scored 4+.
Thanks to @Yesiamaduck for taking my suggestion to cover this series.
Currently doing a replay of the series and have been looking into the romhacking end of things to see the things fans have come up with.
The ‘fixed’ version of Simon’s Quest seems fine and then I found this:

A brand new classic NES Castlevania game made by fans by doing romhacks.
New levels, enemies etc.
