Fallout 4 is their biggest game and it's a generally accepted opinion that this game was a massive disappointment and a step back from its predecessor in every way.
Fallout 76 was a disaster.
Prey, Dishonored 2, Evil Within 2 and Rage 2 were all commercial bombs. That means gamers don't give a shit about those franchises.
They turned Wolfenstein into Wokenstein and destroyed it with left wing agenda politics.
So the only good games they've actually released all gen have been the 2 Doom games. And even Eternal just came and went like it was nothing. No one would even remember it came out this year if Ghost didn't make a daily thread about it.
People are really overvaluing Bethesda's importance to the industry now. If their games were lighting up the charts then they wouldn't have been up for sale. They needed someone to bail them out after a generation full of misfires. Now they can continue to make monetized garbage like Fallout 76 except now it will be on game pass with Microsoft's other shovelware.
