I have too many other games I get hooked on for a bit, like Sim City, The Sims, Roller Coaster Tycoon, Pokemon, Locomotion, Civilization, and so on.
I always found it easier to play than YGO, but I did learn how to play it before YGO. I also learned how to play MTG before learning to play YGO, as well as the short-lived Harry Potter TCG from Wizards.
