Oh yeah, they are. Well, Blizzard/Activision/Bungie, EA, Valve, And Microsoft. This is ZeniMax's stab at a game as a service - their WoW, their CS:GO, Their Anthem / Destiny / Halo: Infinite.
If 76 goes to plan? There will be no Fallout 5. Just an acceptably profitable zombie perpetually idling for decades on end with free but unsatisfying story DLC until it's no longer lucrative to keep the servers on. And if the game does not pick up enough momentum to be profitable in the three months, they'll flip the kill switch on the franchise anyway. On to bigger and better earners like Starfield, no time to mourn or make amends for non-breadwinners. Just a bayonet to the gut.
