As the wait for news on the next Half-Life game goes on, Valve boss Gabe Newell has explained the famed developer's current strategy on revealing new titles.
Valve's experience with Half-Life and Half-Life 2 caused a rethink, leading the company to back off from talking about future games until they're good and ready, Newell told Penny Arcade.
"Part of the reason that we backed off talking so much about what was happening in the future is that when we've done that in the past, you know, with Half-Life 1 it was a year after we originally said it would be, Half-Life 2 basically if you go and read the forum posts apparently took us 50 or 60 years to get done, so we're trying to be careful not to get people too excited and then have to go and disappoint them.
"So we're sort of reacting in the other direction and saying, 'okay, well let's have things a little more baked before we start getting people all excited about it.'"
Valve's continued silence over the next Half-Life, be it Half-Life 2: Episode 3 or Half-Life 3, has frustrated many of its fans.
Earlier this month 10,000 Valve fans logged on to play Half-Life 2 en-masse in an attempt to make their campaign for more Half-Life information heard. It was the result of a Steam Group, called A Call for Communication (Half-Life), that is lobbying Valve to release more information on the future of the much-loved series.
"The lack of communication between Valve and the Half-Life community has been a frustrating experience. While continued support for current and future products is greatly appreciated, fans of the Half-Life series have waited years for a word on when the franchise will return," the group's description reads.
"We're acutely aware of how much we annoy our fans and it's pretty frustrating to us when we put them into that situation," Newell told Penny Arcade, while agreeing with the suggestion that there is tension between all the various projects the company is interested in doing.
"We try to go as fast as we can and we try to pick the things that we think are going to be most valuable to our customers and if there's some magic way we can get more work done in a day then we'd love to hear about it.
"But we recognize that it's been a long time whereas we have so many games that people really love - Counter-Strike, Half-Life, Portal, Left 4 Dead, not a whole lot of Ricochet enthusiasts out there, and at the same time we want to be making sure that those games and those stories and those characters are moving forward while also making sure that we don't just get into terminal sequelitis."
In June 2009 Newell said he had "very good reasons" for not discussing Half-Life 2: Episode 3, but refused to be drawn on them or when the developer would be able to open up about the concluding chapter in the FPS saga.
"I get a ton of email every day saying why aren't you talking about Episode 3? And there are very good reasons why we're not talking about Episode 3, which I can't talk about yet, but I will," Newell said at the time.
And last year, Newell told Eurogamer he wouldn't trade the "enthusiasm and straightforwardness of our fans for a quieter inbox".
10,000 Valve fans logged on to play Half-Life 2 en-masse in an attempt to make their campaign for more Half-Life information heard.
But that number is far less than the 50,000 users expected to make the gesture.
The A Call for Communication (Half-Life) Steam Group is lobbying Valve to release more information on the future of the Half-Life series - be that Half-Life 3 or Half-Life 2: Episode 3.
Still, the group managed to raise Half-Life 2's player figures during the event to 11th on Steam's listing, with in-game numbers up from the average 3000 active players to more than 13,000, Kotaku reports.
Group members have more than doubled since reaching 20,000 last week.
"The lack of communication between Valve and the Half-Life community has been a frustrating experience. While continued support for current and future products is greatly appreciated, fans of the Half-Life series have waited years for a word on when the franchise will return," the group's description reads.
Valve has yet to comment on the fan campaign. Did you take part? Was it fun?
A fan campaign designed to encourage more Half-Life information from developer Valve plans a mass gameplay session this Saturday.
Steam group A Call for Communication (Half-Life), which boasts more than than 29,500 members, has organised a huge Half-Life 2 play session this weekend, designed to raise awareness of its campaign by boosting the game up Steam's most-played list.
The fan collective aims to encourage information from Valve on when the Half-Life series might return, be that in the form of Half-Life 2: Episode 3 or a fully-fledged Half-Life 3.
Group numbers have swelled from 10,000 members since the campaign first hit the headlines two weeks ago.
A Call for Communication's Half-Life 2 play session begins at 7pm UK time this Saturday night.
"Instead of focusing efforts in a negative and disrespectful way, we have decided to gain Valve's attention by delivering a basic message: 'Your oldest and longest running fanbase would like better communication,'" the Steam group's description reads.
"Hopefully such attention will be recognized by Valve, and the community's voice will be heard."
More than 10,000 gamers have joined the Steam Group campaigning for more Half-Life communication from Valve.
In other words, fans want to know when the series will return, be it via Half Life 2: Episode 3 or Half-Life 3.
"The lack of communication between Valve and the Half-Life community has been a frustrating experience," stated the group. "While continued support for current and future products is greatly appreciated, fans of the Half-Life series have waited years for a word on when the franchise will return.
"So, Instead of focusing efforts in a negative and disrespectful way, we have decided to gain Valve's attention by delivering a basic message:
"Your oldest and longest running fanbase would like better communication."
A Call for Communication, Steam Group
"Your oldest and longest running fanbase would like better communication."
The Steam Group, named A Call for Communication (Half-Life), added that, "Waiting patiently for over four years is a daunting task, especially when E3 comes and goes without any beat of a Half-Life pulse, time and time again."
"Valve had stated that information was scheduled to be released towards the end of 2008, and we believe that if they have chosen, for whatever reason, to withhold this information, fans should at least be acknowledged in some way, regardless of developmental plans for the next Half-Life project.
"The entire trilogy of episodes was supposed to be completed and released by 2007, and if Valve have decided to do other things for the time being, that is fine; all that we ask for is a basic response on the matter, and to let fans know whether or not the current story arc is scheduled to conclude at another point in time.
"In addition: This message is in no way, shape or form attempting to rush the development of the Half-Life series; in fact, most members agree that Valve should take the time needed to deliver a complete and polished product."
The post concluded with a line asking gamers to join the A Call for Communication Steam Group if they agreed with the sentiment.
"Hopefully such attention will be recognized by Valve," the post closed, "and the community's voice will be heard."
Half-Life 2: Episode 2 was released alongside Portal and Team Fortress 2 in autumn 2007. Since then, Valve has produced Left 4 Dead, Left 4 Dead 2, Alien Swarm and Portal 2.
Dota 2 and Counter-Strike: Global Offensive are in development.
Few of those games originated inside Valve, however - most were ideas that belonged to external teams or creators Valve eventually hired.
Some observers suggest that Steam's development has hampered Valve's game development; in building the world's most successful PC game digital distribution service, Valve neglected to create new games of its own.
Code possibly belonging to Half-Life 2: Episode 3 has been spotted in the leaked beta client for Dota 2.
The lines of code are for something called "ep3". Take a leap and transform that to Episode 3, and the code suggests the project lives on.
Not only that, we're also given an insight into some weaponry - an ice gun, a flamethrower and a "weaponizer".
Half-Life 2 was released in 2004; Episode 1 in 2006; Episode 2 in 2007.
Four years and many Valve games - Left 4 Dead, Left 4 Dead 2, Portal 2 - have passed since. And now Valve concentrates on Dota 2 and Counter-Strike: Global Offensive.
The absence of Half-Life 2: Episode 3 from Valve press releases, coupled with suggestions that the runaway success of Steam may have impeded Valve's game development, have led many to give up hope.
Has the boat sailed for Episode 3? Should Valve instead concentrate on Half-Life 3?
The Dota 2 beta client link comes from Vietnam. Lambda Generation has rounded up the data mined from the leak.
