I have started playing Grim Fandango with my kids (7 and 9) after we played through Day of the Tentacle together. Playing old adventure games on the TV and letting people take turns playing is a great family activity!

They aren't native English speakers and the story in Grim Fandango is considerably harder to follow compared to DoTT, so they lost interest a bit after we completed year 1. But as soon as their English skills improve, we'll get back to it, it's one of my favorite adventure games!
