There are so many emotional aspects of the game that a 10 year old wouldn't understand, even though Zelda is totally make believe, their are many concepts you can relate to yourself. I'm sure it is more fun playing it as an adult as a child. I'm only 15, but i can guarentee that i will still be playing it in 10 years, hell, my 62 year old GRANDFATHER is playing Skyward Sword in the other room! You're never too old
You're grandpa is so cool!!!! lol that is cute. My grandpa also has a wii. he gets so frustrated with Link's Crossbow Training. He tried to give me his DS the other day bc "he doesn't have the patience for it"...I've already told him I have one.
