Steam Edition is not a perfect 1:1 copy—some legacy add-ons require minor adjustments—but for 95% of users, it’s the best way to fly FSX today.

Some authorized resellers (like Green Man Gaming or Amazon) occasionally sell leftover FSX Gold Edition keys. After purchasing, you can download the official installer from Microsoft’s legacy site (links available through support forums). Be cautious—many third-party key sellers are scams.
