The point is, the most fun mini-game in My Word Coach isn't all that much fun. But it's still better than reading a dictionary for 15 minutes a day, as are all the other mini-games - even if they do get repetitive quickly. True, it all feels more like doing homework than playing a game. But the incentive to keep going is you do find yourself learning new words. If that appeals, My Word Coach offers a stylishly presented, relatively entertaining way of doing it.
Don't buy My French Coach or My Spanish Coach expecting to have as much fun as you would with something like Zoo Keeper. Nor should you expect the teaching to be as effective as proper lessons. But as tools for improving your language skills, whether you're starting from scratch or have some basic knowledge, they're great.
