Dishonored 2

You can make fun of Bethesda all you want for their save player 1 campaign, which is basically nothing more than promotional pitch of their published single-player games. But at the end of the day, the sales performance of Prey and Dishonored 2 speak for themselves

Sure, they did some bad decisions marketing their published SP games (Why they released Dishonored 2 on November 2016 is beyond me) among other policies, but at the end of the day, they green-lit the single-player games where no other publishers would dare do so. And what did the single-player hungry gamers responded? They refused to buy em for whatever reasons ("Gonna wait for a sale", "Don't want to buy a game that's below 90 metascore", muh principles, etc...)

Its strictly business. Bethesda saw the market doesn't want single-player games with no online components whatsoever anymore and that games with GAAS elements (Be it heavy or otherwise) are the way forward.

And before anyone brings up Sony first party SP games as a metric, keep in mind that they're meant to sell systems which offsets the cost. Third-party publishers don't have the luxury

TL:DR: If you want more single-player experiences, buy them. Even if they're not AAA
