Costume Quest

My wife has a tendency not to realise which games are for children and which are for adults. She'll often mistake Fez for a child's game and Call Of Duty as an adult game. Costume Quest is one of those rare games (although Tim Shaefer is good at being involved in them) that can appeal to all ages. CQ is an adorable turn-based RPG, centred around candy-fuelled monsters taking over Halloween - or according to the adults, older kids, and a missing sibling. It's also one of the few games that I actively seeked out to complete every achievement, and will probably play again this time next year. It's only around five hours, although everything is the game is perfectly judged and feels the right length...in fact this could be Double Fine's best game to date. 8.0/10
