I can appreciate that this line of thinking holds for Anno or Settlers fans, or (primarily German) PC gamers of a certain vintage. However, you will find that outside these groups, the name Blue Byte is not widely known, be it geographically or on platforms like consoles (which makes sense of course, seeing how most of the games were PC-only).
Ubisoft on the other hand is a brand that is globally recognized, which for example makes international recruiting much easier. “Would you like to work for company you probably never heard of” versus “would you like to work for one of the biggest and most recognizable publishers in gaming” is pitch that will get a very different first reaction, and as our ambitions demand that we hire more and more talent from outside Germany, that is an important distinction.
Finally, the image of the German PC-only strategy studios does not really reflect the reality of what we do anymore. Yes, for many people we are still best known as the people making Anno and Settlers, but our studios in Berlin, Düsseldorf and Mainz also work on some of the biggest AAA multi-platform blockbusters on the market, such as Far Cry 6, Beyond Good and Evil 2 or Rainbow Six.
As such I think that the Ubisoft moniker is better suited to reflect our ambitions and projects as studios.
