Timur Bekmambetov might be a more recent example. The Night Watch movies were wonderful. Then he made Wanted, which was expensive dross. The best thing about that movie is that he put a couple actors from Night Watch as supporting cast in it. He’s done one or two things since that rate mention, but going Hollywood made him worse, not better.
Having to ship AAA games isn’t the problem. The problem is the incessant need to only focus on live service games so that they can milk their consumer left and right. Studio executives come in with unrealistic sales expectations, which then means you can only try and make games that have a live service component to generate a constant revenue stream, which then means you can’t make good games anymore. You’re either making games that are similar to other and get lost in the crowd or are forced to differentiate by promising something that’s never done before, which adds scope, risk and budget to the game.
If you noticed all AAA failures in recent times, almost all of them were live service games. Meanwhile the single player market seems to have finally recovering from the neglect it’s gotten in the last decade.
Also, look at the BioWare successes and failures. They did well when they did single player games, failed when they ventured into live service.
