Did they have to, though? This was supposed to be the final for Half-Life 2, episode 1 and 2 didn't "solve" any problems. The third one would've finished off the story and Half-Life 3 could've been the one to solve some new problem years later. Them actually making the game didn't mean they'd have to force anything, episode 1 and 2 weren't forced.I'm glad valve shifted gears when they knew they had to. It would of sucked if they forced out an episode 3 and it ended up being bad.
they took the right approach imo.
They straight up just never made the next instalment and went radio silent for 13 years, that's not what I'd call the right approach. That's not even in the same galaxy as right.
