Ha, funny thread with funny replies so far. I've been doing this for a few years now. I'm doing ok too I guess. Games are not the source of inspiration, they're just another reason it's valuable to have the knowledge. (It's also my fourth language, I still have room up there to cram more words in yet another language...) I will tell you this: once you have some foundation, playing things like RPGs help you because of the exposure, the reading practice, and if you have a dictionary on hand you can start picking up new words.. It's funny to me sometimes because I can remember a word not just from the past but also how I learned it. For example I can look at 熟練度 and remember learning it because of Final Fantasy 2.

My language skill only improves so I'm basically fearless when I buy a new title. I don't care how much text there is, I can handle my way through.
