I am very pleased with SEGA Europe building a RTS empire. I am not big into the genre, but I have a lot of respect for it and I like how SEGA is slowly forming a monopoly on the genre, and allowing the studios to develop games that they would otherwise be unable to without SEGA (like Alien: Isolation).
I am, however, worried that SEGA Europe might use this too heavily as their identity moving forward. SEGA of America has it right, with several localized Japanese titles, the PC stuff from SEGA Europe, and cutting off SEGA of America from farming out terrible home console games (Rise of Lyric, Marvel, Golden Compass). SEGA Europe needs to recognize that this isn't the only thing that SEGA can be in that region.
