Simon's Quest is a sequel spawned mainly by the popularity of Castlevania, which by 1988 was already an NES classic. In preparing this follow-up, Konami learned that it hadn't even scratched the surface as to how far the NES' limitations could be stretched. It's for this reason that Konami wanted to try something a little different, which was a theme for sequels from around this time. Thus, Simon's Quest is presented to you not as a stage-by-stage experience but rather as an adventure-RPG in the vein of Metroid and to a greater degree Rygar.

Your objective is to search through numerous haunting scenes to find and explore five progressively challenging mansions, wherein you'll search for the five body parts of Dracula needed to enter the dreaded Castlevania. You'll find your way by interacting with supporting cast members scattered game-wide; by collecting valuable weaponry; by battling and defeating an assortment of enemies to gain experience and thus increase your power-level; and by arriving at the castle to initiate the final battle. Since Simon's Quest runs on a built-in timer, which measures the amount of in-game "days," you can earn different endings depending upon how long your mission lasts.

The Tiger Handheld versions of Simon's Quest are typical of the early LCD-based portable games and are in no way equivalent to the NES original.

Japanese Version
The Japanese version, made for the Famicom Disk System, has a bunch of minor changes:
- The first is the inclusion of a name-entry option that you can use to save your game into a slot and thus the game's memory (in place of the password system we use).

- Because it's a disk game for a disk system, there are loading times present when you enter into towns and mansions.
- The music that guides you along is different in quality (some would argue better); it's more digital, faster-paced, and higher-toned than what you hear in the NES version.
- There are deviations on some names; most prominently, Simon's last name, as is usually the case with the family surname, is "Belmondo." Also, Camilla Cemetery is instead called "Carmilla Cemetery."
- The game's enemy rate is slightly higher than the western version's.
- There are some sound differences: The glass-shattering effect of holy water doesn't exist; the sound effect assigned to Simon falling into a watery pit is altered; the secret-discovering sound plays only when you initially talk to hidden souls and not after; and there are snazzier sounds for the Ferryman's actions and the Deborah Cliff tornado-soul ride.
- You can continue purchasing garlic and laurels even after your stock is filled.
- The mansion music also plays when you're at their outside entrances.
