I bought this game hoping it would help to improve my spoken french, anticipating the creative use of the multi-media DS platform. I was sadly disappointed.
Firstly, the things I thought were good:
The games were easy to grasp and I appreciated the range of methods used to reinforce the vocabulary (anagrams; selecting a word based on its definition; selecting a definition for a specified word; correcting spelling mistakes etc). I liked the fact that there was a daily goal of the number of words to learn and that progress was rewarded with new tasks and increased levels of difficulty. I also thought the glossary review at the end of each task was valuable to reinforce the correct spelling and definition.
However, as the previous reviewer reports, the fact that there is absolutely no grammar (no gender for nouns, no tenses for verbs - even in the glossary) seriously limits its value, as you cannot confidently use the new words without checking them out first in a conventional dictionary. I was also concerned to find that there were some either highly dubious definitions for a small proportion of the words (eg "pension = boards that have been fastened to each other" instead of board/lodging)or obscure definitions for words that have much more common meanings.
Those were the serious concerns, but I also found it very disappointing that the makers had not made more use of the capabilities of the platform, particularly the use of sound for pronunciation (bizarrely, the only use to which the microphone is put is for you to blow on it to raise letters that have sunk in the pasta soup game!). This is a real shame as it would have made it so much more useful and engaging. I would really love someone to do this again properly.
It's still a lot more fun than reading through a dictionary, but not as much use.
