Here are the 4 Intellivision games, and what comes with them:

-Night Stalker: box, manual, both overlays
-Space Battle: box
-Sea Battle: box, manual 1 overlay
-Major League Baseball: box, manual, both overlays.

I'll ship them anywhere in North America for $10 US (including shipping). That comes out to $2.50 a game.

OR...

I'll give them to you for one common NES game that I don't have, providing it is:
A) COMPLETE, and
B) near MINT condition.

If interested, shoot me a PM.
