Before you buy this game, make sure you are buying it for the RIGHT reasons. This game is amazing, exactly the kind of learning style I love and was looking for.
If you are buying this game to learn how to speak fluently (For me, fluent Japanese) by solely relying on this game and nothing else, you will be very disappointed.
If you are buying this game as just one of the many tools to help you learn a language, and you consider yourself a visual learner, then this is perfect in my opinion.
Being able to click any object in the house and instantly be told what it is called, is the next best thing to having a native speaker with you while you point at things asking what they are called. As a huge plus with using the game, you see how it is written; in Romaji, Hiragana, or Kanji depending on what you pick if learning Japanese, which helps a lot more for me personally than just hearing audio alone. Oh and I highly recommend only using Kana instead of Romaji, you will be glad you did in the long run.
The time challenge mode turns the game into a scavenger hunt, making your brain work to remember what each thing is called. I feel that having to recall something, especially with a clock counting down, helps you memorize the words.
Alongside basic nouns from clicking on things in the environment, you can also unlock adjectives and verbs associated with each noun. I really like that because it adds context in a way; like clicking on the word "bed" has the verb "to sleep" available to learn.
So in the end, please use this game as a wonderful tool to master your language alongside your many other tried-and-true methods. I am certainly enjoying it and I feel I am memorizing the words much quicker than looking at definitions in a book. The audio is also very clear and easy to understand.
As for any negatives, I just have a few suggestions rather than anything actually negative. It would be nice if you could do the time challenge mode where objects light up and you have to type in what the object is called, or maybe choose from a multiple choice list. Right now it is just one direction, you hear the word and click the right object, never the other way around. Also if there was an option to have the speaker say the word again but slowly, to catch those quick syllables.
Weather you decide this game is for you or not, please go out there and learn a new language! Trust me, it feels amazing! :)
ATTENTION, NEED TO KNOW TIPS: When doing the time challenge, you have to DOUBLE click an object to select it as your answer. I don't think it tells you that, or I didn't notice. :) Double clicking outside of the game mode, will bring up a window with more details on that object/word you are clicking. Also, when you click on your vocab list, click a word, and there is a little "eye" icon you can click to see what the word is in your native language. I also HIGHLY recommend reading all the hints at the top left of the screen to get the most out of this game, it doesn't take long to read them all. Have fun all!
