If you are a regular tamagotchi user, you will be able to figure out how to use the tamagotchi. However you will not be able to understand what the characters say to each other as it is in Japanese.
You will deffinatly enjoy the ID L. It has so many features such as going to the store to purchase items such as dresses and other outfits for your character to wear. You can also download new games, snacks and other items from your pc onto your ID L buy use a imfared adapter, or by using a mobile phone. You can also buy new backgrounds for your ID L as well as making them in a programme that you download onto your pc. I would recommend getting one of these as it does add a lot more fun to the Tamagotchi.
