I have a copy of their Sensi book which I backed on kickstarter back in the day. It's a neat book, but somewhat lacking as narrative read, being interview based. Different interviewees give different and sometimes quite contradictory recollections of significant events, which can be frustrating if you try to read it from cover to cover ever. Maybe as a coffee-table book to dip in and out of it might do, in terms of the text, and it certainly seems to have the graphics for that. And maybe it's more of a problem if one of your interviewees happens to be Jon Hall, I dunno.
Also, the picture of the dreamcast mockup with moobs gave me a laugh
