History of Sega
From Sega Retro
I think it was the right call to remove the duplicate mini-histories of certain Sega products from the Sega page, but I wouldn't bother maintaining a big "History of Sega" page like this - the subject matter is too big.
More detailed history is better suited to the contents of Category:History, or, for specific products, pages like History of the Sega Saturn or whatever.
A rough timeline of important events might be useful, but I'd probably stick that back in the Sega page. -Black Squirrel (talk) 12:02, 27 April 2017 (CDT)
