They’ve admitted to cancelling ideas before, getting to various stages of production before going back to the drawing board, but always (and appear to still) insist that it is in development on some level. That’s why Newell’s responses to questions about hl3 are usually some form of “we have nothing new to share.” Valve doesn’t like sharing until they’re in the final stages of development, and hl3 has never made it that far.
Leaving it to rot for 15 years was far more unjust than a slightly less “revolutionary” game. And the concepts they show in the new doc are cool as hell! I would have loved to shoot at blobmonster! They just decided singleplayer FPS games weren’t as profitable, and that’s fine, I guess. They’re a company, they want to make money. But pretending they were somehow doing us a favor by leaving the cliffhanger for so long is utter nonsense. Especially since they wound up simply retconning it so the whole wait was pointless anyway!
Edit: y’all they literally said in the doc that if they’d kept working on it for 1-2 more years they would have been able to complete it, but they were more interested in multiplayer games and went to go work on that. But if you really want to drink the self-aggrandizing bs that Newell spouts, go right ahead
