I'm playing Final Fantasy 7 in both English and Japanese at the same time, and noticing a bunch of tiny differences — for you. Here's a video illustrating what nuances of the first few lines of the game couldn't make it into the English translation.
I lived and worked in Japan for 10 years. I've worked as a game designer on Japanese video games, and I've even officially translated a Japanese role-playing game from Japanese into English all by myself (it was a lot of work...). So I had a real good time making this video — and there's more to come!
