Hey everybody!
I'm currently working on a game called gaijiN5 that you might be interested in! It's a Visual MUD game to teach Japanese by immersion using various memory and psychology tricks to make it stick.
It's currently in it's Kickstarter phase right now, but funding is vital to setting up a team rather than making it a one man show(which I'll still do if I have to cause I think the idea is great). I was hesitant on evangelising to forums as I see a lot of subpar projects do, but I can't think of any better way to get the word out about it(I'd love to hear suggestions).
Also I figure by reaching out, I can answer any questions you have in your own environment!
I'm sure when it is completed you will find it to be a very efficient and fast way of learning!
