For the most part, I quite like Sweeney. He's one of gaming's quiet visionaries - almost the opposite to loudmouths like Peter Molyneux - and seemed to take a very "gamer first" approach to game development. CliffyB's autobiography gives a very positive account of him too.
His approach to business is quite concerning though. Whether it's complaining that the barriers to developing for Linux is too high while simultaneously cutting 10-12% of his workforce, to articles like this where Sweeney talks about the Fortnite ecosystem - it's just becoming increasingly anti-gamer. Fortnite is part of the ecosystem, not the ecosystem - no wonder we're being driven towards AI slop in games, because everything else is getting choked off.
Am I preaching to the converted? Probably. Maybe I'll just play the Epic Megagames series as far as Gears of War and pretend the last fifteen years or so never happened
