Hi there! I've been teaching myself some Japanese for a bit and although I haven't learned very much, I am still loving it.
My motivation for learning Japanese is career/entertainment oriented. I love video games, and there are many titles that are never ported over to North America or the PAL region, so the only options to play them are to get someone else to translate the entire game for you, or just do the translating yourself. I'm going for the latter. I'd like to ultimate work in the gaming industry, possibly in journalism (writing about games, reviews, previews, and the like).
Obviously I'm not going to learn all that I need to read over night. I've gotten down all hiragana and am starting on katakana (I'm starting to learn some kanji as well). I don't know enough grammar to structure anything beyond "Hello," "Nice to meet you," and "ビデオガームがすきます。"
What I'd like help with is this: what common words are used in games, what sort of ideas I should be familiar with, what key grammar points should I absolutely learn, are there any simple games I could try to help build my Japanese, and any other points that might be vital to my success.
I should probably also mention that the specific type of games I am interested in are RPGs, the ones with rather in depth story lines. So if you have no idea what video games usually are like, I can deal with vocabulary and grammar usually associated with fairy tales and medieval chivalry stories. Stuff like that is somewhat close to RPGs.
