The HL3 memes don't even seem fair to use anymore. I don't even want to un-seriously make joke fun of them at this point. They are just genuinely doing so much for the community.
It's absolutely fair to mock them for not releasing these games and keeping radio silence all these years. They managed to dethrone Duke Nukem Forever.
There were multiple times in which the internet was hyped for Episode 3 and where it would make sense to release even a basic game like they've did with Episodes 1&2 just to wrap things up. I'm sure plenty of people that make up various explanations to why that happened but the end result is that Valve has chosen to disappoint the fans who have been waiting for the conclusion to the story. It's not like doing that would prevent them from releasing an another new entry in the series that uses revolutionary new technology or whatever.
They have only one chance of publishing HL3, and I hope put in it the same love and care they put in 1 and 2.
I'd be very disappointed if they just released it just for the sake of releasing it.
But then why release Alyx as VR instead of HL3? What innovation did HL2 episodes 1 and 3 offer? Why are Valve releasing virtual card games today?
Half Life as a franchise is great. Gabe was right to start nearly from scratch on HL1 back in the day. But now, they've got everything they want so the hunger is gone.
