I really think a christmas themed pinball could work. Thought about it the other day because our front living room where we normally put the tree up is filled with 3 pinball machines currently (and my wife teases me about it, but I know if I put them in the basement they won't get played as much). If I had a christmas themed pinball, I wouldn't need to put up a tree necessarily.
Features:
Christmas trees GI lighting complete with ornaments fill the playfield
Snowman artwork on the playfield (House with dead christmas bulbs that need to be relit, christmas tree in the window with ornament inserts)
Real jingle bells that ring in the bottom of the cabinet (ALA space shuttle bell)
Goals:
Get the santaball through the chimney scoop
Fix the bad bulbs on the lights on the house (one light goes out, they all go out)
Light up the christmas tree
Go to all the stores to look for presents on your list
Bad behaved kid mode means coal in your stockings
