Hi, I received it during the weekend and I started reading it. Seems to be well writtern and with lots of contents, but so far (first 40 pages) seems to lack a bit of "personality". The focus is almost totally on the consumer history of the company, while the arcade part gets only a short introduction. One thing I didn't like is that the description on Amazon says "high quality images" while in fact we have B&W, slightly blurry pictures. However, if you're interested in the history of Sega (and can't read, like me, the great Sega Consumer History and Sega Arcade History books in japanese) this is a must read.
