We acquired Settlers of Catan this year (we add a decent board game to the collection each Christmas). It requires just the right amount of thought imho, so even FoL2 (aged 6) can join in, even if he’s a bit shit at it.
Yup, we’re acquiring quite a collection now. Just need the kids to be a bit older and I can go mental on Arkham Horror and its umpteen expansions. It at least has the advantage of being a team co-op game, so helping small people is part of the vibe.
They are playing 221B Baker Street now. I have been excluded because I wouldn’t promise not to cheat (after explaining that cheating was mandatory in family board game sessions). It looks like we might be having a go at Whist next. My Dad used to love cheating at that…I’ll definitely have a hand or two of that.
