Sigh, I'm starting to notice a trend here myself.
"Oh look. The opinion and tastes of our demographic is shifting! We must go online and say misleading things hoping someone does what we want so we don't have to adapt accordingly!"
That's... partly a subversion of humanity. Life itself actually. When the Ecosystem changes, you don't tell the Ecosystem to stop and behave as if it's a spoiled child. Or If it's raining, you don't look up and tell the sky to hold it. You observe the Ecosystem and find another way to fulfill your needs, if it's raining you get inside a building faster.
Sci-fi isn't getting saturated. It isn't seeing more titles just now, it has ALWAYS seen more titles in videogames because you can do pretty much whatever the hell you want there. Artificial Inteligences? Sure. Alien species? Sounds about right. Laser crossbows? Knock yourself out. Lightsabers? Yes please. It's pure fiction, you're not beholden to make every title like Halo, and in fact, people don't: Some settings have different species; in others the way human beings live or interact is different; in some cases, humanity is removed altogether and a completely different species, different culture and everything that implies are the protagonists; among others. It's called Science Fiction for a reason.
But Spunk Gargle Wee Wee's? You play one of them and done, commit it to memory and you've seen them all. Guns won't change, the reason for the portrayed conflict is always something like terrorism or a country starting an arms/supplying race, everything is a shade of brown/gray, the characters you interact with have as much personality as a cardboard, among others. Rules are so rigid in a SGWW that if you break a single one, it actively STOPS being a Spunk Gargle Wee Wee game, which is a term that has more personality than most of the titles it portrays, because it's funny. The single time I've seen someone do anything at all different with SGWW's was Spec Ops: The Line, by viciously deconstructing the genre, the protagonists and even the players.
SGWW is a Mold. You've seen it once, you know what you're in for. In SciFi? There's a single rule: Something central to the setting must be as of yet undiscovered by mankind, from something simple as a new fuel source, to something extreme as the Setting being in a different Stellar System, or Galaxy.
No, you're keeping Battlefield as a SGWW because it's one of the only 2 series that profit in that genre. That's fine, you want money. But don't look at everyone else moving away and say they're doing it wrong. If you hadn't been as lucky, you'd be doing the exact same thing.
And then, you'd probably go online, saying something like "Modern Military Shooter games don't work, it's a dying genre".
