Board games can be fun if you are with someone who is at the same level or better than you. Then you can learn and develop, and it is also interesting.
Once I went over a friend's house when I was about seven or eight years old. She wanted to play topple for hours. At first, I tried to be diplomatic and play, but after a while, I just said (in what must have been a totally arrogant-sounding voice) "Can we play something a bit more challenging? Something more intellectual?" An eight-year-old. Hell, she probably didn't even know what I meant by the word. Then she brought out Sorry! GAHHHHH!!!! I was used to playing scrabble with my grandmother, who was an English teacher. I lost like hell. But it was fun and GREAT. I was playing games like cribbage and 45s at ten and bridge at sixteen (okay, card games, but same idea). It was a challenge, and I LEARNED something. Here this kid was breaking out TOPPLE!!!
Sheesh, I would have slapped myself silly if I had seen myself back then, but being a kid, I guess I was much more honest and much less diplomatic. Damn, I was really an arrogant ass...good that I learned to calm my butt down a bit.
So I agree with the people who said that the following things matter:
1. It must be a challenging game I'm interested in. Not monopoly, where it is clear that you just buy everything in sight and buy from people too stupid to know any better. WORD games are fabulous, as are certain strategic card games.
2. You must play with people who challenge you, or it is boring as all hell.
That's my opinion, anyway.
P.S. Now I can kick all my family's butts at scrabble. So it must have taught me something. (Okay, I am also a nerd and play it to death on scrabulous, but oh well.)
