For the astronaut in all of us. Although I play board games for the fun and the notsalgia, there's a sizeable community of vintage collectors.

The Lost in Space game pictured here is one of the valuable ones, depending on condition of the box and board. But the 3-D Lost in Space, which resembles the 3-level chess set from Start Trek: The Next Generation, can fetch well over $1,000 in good condition.

I'll just stick to the $20 special that my kids can gum up, thank you.
