I notice you're having problems with Dracula 3 over in Hints.
I don't think you'll have these kinds of problems with either of the first two -- or with Dracula 4 and 5 either. In my opinion Dracula 3 was the most difficult. If I remember right, events might not trigger the same way on different playthroughs, and following a walkthrough step by step might not be possible. I played using a walkthrough, but I had to skip over parts of the walkthrough when options weren't available, and go do something else in the game. Eventually options would be triggered and I was able to go back and take care of things. I'm not sure if this was a deliberate "feature" of the game or not, but it was a PITA.
I played Dracula 3 and Dracula Origin and didn't think either of them lived up to The Last Sanctuary or Resurrection, although Origin was pretty good.
I don't think Dracula Origin can be directly compared to the others.
The games had a different "feel."
Origin was fun, but not as spooky as Dracula 1,2,3.
