The Simpsons: Bart vs. The Space Mutants
Sega Master System · 1991
About this game
The Space Mutants is a platform game where the player goes into the role of Bart Simpson (from the TV show The Simpsons) and must stop the Space Mutants from invading Springfield.
On each of the five levels, Bart must collect (or get rid of) the ingredients that the Space Mutants are planning to use to build their machine, such as purple objects or balloons.

He also has to collect enough "proof" of the aliens existence (brown coins left behind when they are jumped on), so his family members will help him when he meets a boss (characters such as Nelson and Sideshow Bob).
This won't be easy since the Space Mutants are "using" human bodies as disguise.
In order to discover who are the real Space Mutants, Bart must use his X-ray Specs.
About Sega Master System
The Sega Master System (1985/1986) was Sega's answer to the NES and, while it lost the console war in North America, became genuinely dominant in markets like Brazil and parts of Europe. That regional split matters for collectors: PAL and Brazilian-market cartridges can differ meaningfully in scarcity and pricing from their North American counterparts for the same title.
Gamevaro tracks The Simpsons: Bart vs. The Space Mutants for Sega Master System with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding The Simpsons: Bart vs. The Space Mutants to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This SMS release dates back to 1991.

Rarity & condition
Only a handful of market sales have been tracked for The Simpsons: Bart vs. The Space Mutants, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Sega Master System titles.
Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
