Great topic!!!
Although, "mastered" could mean alot of things.
This is probably the first game I felt I had "mastered."
RIVER RAID!!!
now, the first game I truly ever beat, at least the first game I finished that had a true ending is...
THE LEGEND OF ZELDA!!!
(I still have my original gold cartridge and it works in my original NES, yay!)
