Is it niche though?
Can you name 5 genres that are more popular than Extraction today?
Yes, fair enough for PC. But not for console.
I think it's more that Bungie are, for better or worse, near the very summit of developers. Their games should be as inviting as possible to encourage millions of sales and hundreds of thousands of players.
Destiny, at its best, catered to all audiences. A casual player (like me) got 100s of hours levelling, collecting guns, running strikes and playing crucible. And then there was an entirely different world of dungeon and raid players, alongside competitive pvp, that essentially offered a different game. I absolutely *hate* the word, as it's corporate bullshit, but they managed to design an 'ecosystem' that catered for a variety of gamers.
Marathon does not feel like it shares that design philosophy. I was hoping for an extraction shooter that offered a playstyle that could, for a bum like me, be effectively pve. A little like a patrol zone in Destiny 2, where you just run around, shoot stuff and grind out experience / loot. PvP could be easily avoided whilst maintaining lots of stuff to do. This feels like full on extraction sweatiness.
As I say, for fans of the genre, it might be perfect. But I'm surprised that a developer that has a vested interest in welcoming as many players as possible (especially on console) has created such a high barrier of entry to enjoy their title.
