I'm motivated to learn Japanese because there are a lot of Japanese exclusive games I would like to play. I already know a lot of kanji, actually, I would assume most kanji. Does anyone know roughly how many words I should know in order to play JP games with 80-90% comprehension? And roughly how long it would take in hours? I'm not planning to play any JP intensive games like RPG. Thanks Edit: I know Chinese. I suppose I should have clarified that. Most of the Kanji are very similar to Chinese in meaning, though I would have no idea how to pronounce it. I have tried playing JP games. I can guess and deduct meaning but because I don't know hiragane/katagana, I'm screwed for all the non-kanji letters. Besides, don't I need to know words, which are made with a combination of the 3? Which is really what I'm asking... How many words do I need to know? And I find that grammar structure btw the 2 languages are also very similar. So really, I need to get the words down.
