My 5-year-old nephew loves to play go fish, war and Uno.
He also loves Pokemon Snap for the N64, and Monster Rancer 2 for the playstation, but I don’t know if you would want to encourage that. Kids seem so focused on the TV as it is.
Forgot an ‘h’ there. Rancher. Monster Rancher 2.
I’m having trouble remembering being six, but is he perhaps ready for Risk?
If you’ve got another player or two: Apples to Apples: junior? Hare & Tortoise is a surprisingly deep game that seems like kids could grasp it. (a.k.a. Hase und Igel(sp?)
Connect Four, Clue…???
hmm… tough question…
Postal 2?
