Mainline Metroid games are few and far between, and the franchise has an iffy history with spin-offs. While Metroid Prime proved Samus Aran's bounty hunting works in a first-person shooter, spawning its own subseries, there are many other reviled attempts to tell stories across this universe. Metroid: Other M is largely known because it butchered Samus' characterization for many, and Metroid Prime: Federation Force came out at a bad time for those anxious to see games starring Samus.
