Which Switch games are considered rare?

I can't remember if Rondo of Blood was one of the Castlevania Collection games. It wouldn't make sense to release it separately if it was. (had to have the NES trilogy, SCV4, Bloodlines and Kid Dracula. Were the remaining two Rondo and Haunted Castle?) No, probably not because I think the GB trilogy was in there somewhere. Maybe it was just the NES, SNES (excluding Dracula X which I recall they saved as bonus for the Advance Collection) and GB games.

I think PS2 REZ reprint answered that question. IT was rare selling hot, and then magically a fresh batch was printed. So now we have two copies floating around,. However that was like a slap in the face from the publisher. They think "people buy REZ to play it" when people not only play it but collect it.
So if the Switch did the same thing would it matter?

Question? if a game is ported to the Switch and it gets a remake which is on PC, which version matters?

It is like GCN and Beyond Good and Evil or PSO. If Ubisoft and SEGA had focus on the GCN alone would it be a better game and would have been more collectable, because the fact you can still play those games on a Wii. We would have BGAE 4 by now.
