We haven't really played board games recently, but we do have the following:
Triominoes
X-Files (can't remember the name, it's got a video)
Dungeons & Dragons (based on the cartoon)
Frogger
Cluedo
Simpson's Cluedo
There's probably more, but I can't be bothered to go downstairs to find out :-P
Oh, we used to have Ker-Plunk when I was a kid, been thinking about getting it again recently :-D
