There are a few games I'd like to watch my future kid play just to see his reaction. Shadow of the Colossus is #1.
(I mean if you like to see them play, even if they don't.)

I have a bunch of those in mind, but primarily:
Final Fantasy VII, VIII, and IX
Sonic the Hedgehog 1, 2 and 3
The Ace Combat franchise up to Ace Combat 3.
FYI, there are other games that I would want my future kid to be exposed to, but a lot of them I played as an adult, so they don't really count (seeing the question requests games that I played as a kid).
Here are some of my favorites:

I wrote them in orden of importance, the way I would be handling them over to them as they grow old. Also so they can apreciate the evolution of games hehe. Basically every game I've played that I've enjoyed. There are some I didn't liked so I would forget about those.
