An interesting interview with creator Tetsuya Takahashi from February this year by the Japanese denfaminicogamer site has been translated by Lugalbanda, and while it is not specifically a Xenogears or Xenosaga interview, it is a general Tetsuya Takahashi interview that goes into some interesting stuff about Xenogears and his time at Square and so I've decided it belongs on the study guide.
The information revealed in this interview has also compelled me to update the History of Xenogears article, adding some of the new information and quotes.
There may also be more interviews coming up from the Xenogears 20th Anniversary Concert pamphlet from the same translator, so stay tuned for that. Accordingly, I will re-arrange the interview order slightly and divide them up into more specific Xenogears and Xenosaga related interviews, and I will place the Xenogears interviews at the top since the latest interviews mostly concern Xenogears as well as Xenogears being the more popular work.
