Outlanders

The young princess of the invading army, Kahm, comes to Earth to take part in the annihilation of the human race.

She ends up stranded on Earth, where Tetsuya finds her, and they fall for each other.

They decide that if they were to get married, the two planets would no longer be able to fight, and so they set off for Kahm's home planet to seek permission from her father, the emperor.

Having been the one who ordered the invasion in the first place, though, he is not particularly pleased with this turn of events.

Tetsuya is imprisoned, and Kahm is taken away to places unknown.

Now, Tetsuya must break out of prison and rescue Kahm! Outlanders is an action RPG based on the manga by Joji Manabe.

Tetsuya, being just a regular guy, isn't a particularly able fighter, and at first is only equipped with a sword, though he can eventually find other weapons including a gun.

At the beginning, Tetsuya's only companion is the brown, cloaked alien Nao, who helps him escape the holding cell, but eventually he will find others who will help him.

Other standard RPG features are also present: items can be found and stored, and some characters can learn magic.

The game uses a password system to save progress.

Outlanders for Nintendo Entertainment System is currently worth €17.11 loose, €107.40 complete in box, and €343.68 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Outlanders has a steady sales history on the tracked marketplaces, meaning it trades hands regularly and isn't considered particularly rare.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Outlanders, loose is €17.11 and CIB is €107.40 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.
