Okay, first off, he’s holding the Tomb of Horrors module, written by the great Gary Gygax. (I’ll post it in my module series next year.)
Next, we’ve got two Lego Space sets: the Mobile Rocket Transport (6950) and the Surface Explorer (6880). (Images are via Brickipedia.)
Top Secret was a spy vs. spy RPG released by TSR in 1980. Rubik’s Revenge was a more difficult version of the Rubik’s Cube (I so hated those cubes). And of course that Pitfall is the original Atari 2600 version, released in 1982.

You ain’t seen nothing yet!
This kid made out. It’s safe to say this was one of his best Christmases ever.
Great picture. I remember the joy of getting D&D stuff for Christmas! Heck my oldest just got me a neato set of dice – so still have that joy!
