Hey man, if you're gonna ignore most of my argument, then I'm not gonna respond to yours. :V
Seriously though, my main point is that SEGA isn't nearly as creative or diverse as Sony, Devolver, Adult Swim Games, or even Ubisoft. Sure, they put out some creative games, but every game company does that. And they don't need to use literal sandboxes to be diverse. And if the only thing that makes SEGA more diverse than a company like EA is two or three original arcade games in the last few years, then maybe they're not actually that diverse anymore.
I can agree on Devolver and Adult Swim Games, but it's harder to justify with EA though, Unravel is nice but it's not like SEGA hasn't published low risk new IPs either, they had like 4 or 5 new IPs in Japan for 2014 and a couple set to be released this year too (I'm specifically talking about consoles here.) it becomes tougher when we throw Atlus in the mix too which just bulks up the main groups creative output.
EA's release list for 2015 is: The Sims 4 expansion, Need for Speed, Battlefield, Dragon Age, Madden, NHL, FIFA and Battlefront
SEGA's release list for 2015 is: Total War expansion, Yakuza 0, Tembo, Project Mirai 2 Deluxe, Shining EX: Blade Arcus, 7th Dragon 3, Sonic Fire & Ice, Stella Glow, Football Manager 2016, Miracle Girls and Dengeki Bunko Climax: Fighting Climax
EA's: Life management, Racer, FPS, RPG, American Football, Hockey, Football and Tactical FPS.
SEGA: Strategy Tactic, Brawler RPG, Platformer, Dance Rhythm, 2D fighter, turn based RPG, Platformer, Strategy RPG, Management, Dance Rhythm and 2D fighter.
Taking out the Japan only products it becomes: Strategy Tactic, Platformer, Dance Rhythm, Platformer, Management and Fighter.
Looking at it as solely SEGA West's console games vs EA's console game, the latter comes out on top, adding in SEGA's arcade, Japan only products and Atlus though, their line up is more diverse. EA obviously has the bigger budgeted bombastic line up though and stuff like Unravel is probably more creative than some of SEGA's new IPs. I'd check later on with Sony, who I do think should be more diverse and creative, but I'm not sure about Ubisoft.
I do agree with your initial point though, if SEGA DNA is diverse and creative lineup then Sony and even Microsoft have always had SEGA DNA since their entry into console development, let's not forget some of the oddball stuff Sony has been making/funding since the Playstation 1 era. Really it's a silly comment that holds no barring in reality and nothing about games like Daytona, Streets of Rage or Shining Force are "creative" either, just games made better than or response to their competitors in the market.
