Alan's post reminded me (and sorry of this is a tad off-topic) but, years ago, a few of my friends and I would get together every Tuesday night for board games - Pictionary was one, but also Risk, Trivial Pursuit, and a few others I can't remember right now. It was simple fun, but effective (and, importantly, cheap, since we weren't rich).
I sometimes play an old arcade game, Galaga, on a MAME emulator - it's good for a bit of light fun.
At the moment my favourite game is "gunna" - that's all the computer games I buy, install and that I'm "gunna" play when I get around to it ....
