I enjoy the odd boardgame with friends. I could go a round of Trivial Pursuit, or perhaps some Cranium, or even the odd thrash at Lord of the Rings Risk (that one I can highly recommend: Risk with a twist if you will). I even recently dipped my toes into The Davinci Code Game, which I could recommend maybe to the slightly-masochistic cryptic crossword afficionado with a spare day or three.
Deflexion however looks like the sort of game that I would play once, then spend the rest of the day just aiming fricking lasers at everyone and tormenting the cat. Perfect!
