I'm 38 yo, but we rented this for the kids & even I had a great time with it.
It takes some practice with the WII remote to get the movements just right to perform the cooking steps - peeling & chopping vegetables, fruit, meats; stirring & mixing ingredients; cracking eggs; pouring mixes into containers; etc.
Overall I gave this game a 9, because it was fun, there's no violence whatsoever, & it taught my kids something really useful, that being that cooking can be fun.
Since we rented this game, my kids (7 & 10 yo) are asking more to help w/ the cooking & learning about measurements, reading recipes, kitchen tools & oven safety. This IS a mild game, but it's highly entertaining & my whole family enjoyed it.
