They have however refocused on cash-cow live-service games rather than the polished single player experiences they were originally famous for. In the 13 years since Portal 2 they've only released one single player game, and that one was driven by their company-wide VR push more than anything else. It's harder to get excited about their games when they no longer want to make anything that can't be leveraged into an infinite money siphon.
They've also had an uptick in disastrous flops with Artifact and Underlords, hopefully Deadlock will be a return to form.
