Erik Wolpaw is best known for co-writing the iconic Portal 1 and 2. It’s been years since Portal 2 came out in 2011, but he has voiced out an interest in making Portal 3. However, that might be nothing more than a pipe dream right now.

According to a report by VGC, Wolpaw spoke on the Kiwi Talkz podcast, saying:

“We’ve gotta start Portal 3. That’s my message to… to whoever. I am not getting any younger. We are reaching the point where it’s crazy to think [that we’re] literally going to be too old to work on Portal 3, so we should just do it.”

However, he also said that it will not be easy for Valve to greenlight a Portal 3.

He added:

“Oh yeah, I would love to. I’d work on another Portal in a second, but I can’t make it happen by myself. “Oh, I could advocate for it […] it might help a little bit, but the problem is [Valve has] 300 employees and I don’t know exactly the breakdown – how many of them are on the production side versus Steam business side versus legal versus whatever.

So there’s a lot of opportunity cost to taking 75 people and trying to get a game made. As much as it seem like Valve often [is] just a bunch of people sitting around sipping gin and tonics by a pool, everybody’s working.

They’re working all the time, it’s just you don’t always see the [result], it doesn’t always end up coming out, or it comes out years later, it gets turned into something else. So everybody is accounted for, I guess is what I’m saying. People are all doing something.

So you’d almost have to take them – it’s like a revolution – [and] stir up a bunch of people to leave what they’re currently working on and come work on something else, in this case it would be Portal 3.”

Then, there’s also the question of whether Portal 3 would be profitable enough for Valve. It would likely make a lot of money, but Wolpaw said that Valve might expect more, like “Counter-Strike Global Offensive” levels of money.

He continued:

“Hey, you’re preaching to the choir here, you’d make some money.

The problem is, you would make money, but what kind of money will you make? Are you gonna make Counter-Strike: GO money? Probably not.

“But having said that, maybe every game doesn’t need to make Counter-Strike: GO money, you know, Gabe, if you’re listening.”
