Gaming QA testers regularly come under fire as bug-riddled games reach the hands of disappointed gamers with seemingly increasing prevalence.

The backlash QA testers receive from frustrated gamers is often misplaced. Managers are often aware that games are full of bugs but decide to release unfinished games anyway in the hope of starting to recoup development costs.

However, proper QA testing is a time-consuming and resource-intensive process. On the PAX stage, Booty explained how a game needs to be re-tested from start to finish whenever a feature is added.

“Some of the processes that we have [currently] haven’t really kept up with how quickly we can make content. One of those is testing,” Booty said.

“There’s a lot going on with AI and ML right now, and people using AI to generate all these images. What I always say when I bump into the AI folks, is: ‘Help me figure out how to use an AI bot to go test a game.’”

If bugs can be caught earlier in the development process, they have a greater chance of being fixed prior to management feeling the financial pressure to send the game to market regardless.

The full ‘Storytime with Matt Booty’ talk can be viewed here. At around 01:02:00, you can hear Booty explain his vision for AI in game testing.

“I would love to be able to start up ten thousand instances of a game in the cloud – so there are ten thousand copies of the game running – deploy an AI bot to spend all night testing that game, and in the morning we get a report. That would be transformational,” explains Booty.

Booty’s core idea of improving QA testing with AI is solid. However, the way it was presented – of replacing human testers – may not go down too well. Mistreatment of QA testers in the gaming industry has led to a growing call for their members to unionise.

The startup has attracted interest for its ability to design and deploy interactive characters with more realistic interactions across the metaverse and other virtual words like video games.

In current video games, NPCs have pre-scripted responses. AI-powered virtual characters like those Inworld are developing can offer dynamic responses to general questions about the local area or wider world.

While graphics have generally become more immersive over the years, interactions have largely remained the same. The ability for NPCs to hold conversations more naturally will be a giant leap forward for gaming and help to deliver on the metaverse’s bold promises.

Inworld’s potentially key role in the future of the metaverse and gaming market – which is already worth hundreds of billions of dollars – has opened investors’ wallets.

Since it left stealth last year, Inworld has raised $70 million. In March, it raised $10 million in a strategic funding round.

Inworld was also notably included in the latest Disney Accelerator cohort which also included blockchain network Polygon, NFT platform Flickplay, AR hardware and interface developer Red 6, metaverse e-commerce platform Obsess, and immersive experience provider Lockerverse.

“I’ve long believed that interactions, memories, and connections formed in immersive worlds can become as real as those formed in real life. It’s why I’m excited about being named a Disney Accelerator company,” wrote Inworld AI CEO Ilya Gelfenbeyn in a LinkedIn post about the accelerator.

“Our platform for creating memorable, AI-powered characters will unlock new opportunities for creators in entertainment, gaming, the metaverse, and other digital realms who are ready to create memories like mine.”

Inworld Studio launched in beta a few months ago. The no-code system works with most common game and metaverse engines, including Unreal and unity.

“It’s crazy to think that Inworld was founded just 13 months ago. Since then, we raised two seed rounds, were selected for the Disney Accelerator, launched the beta version of our product, and now, closed our Series A!” wrote Gelfenbeyn in a blog post.

“It’s been impressive to see our community bring characters to life with AI. I know the best is yet to come.”

Some of mankind’s most complex games, like Go, have failed to challenge AIs from the likes of DeepMind. Reinforcement learning trains algorithms by running scenarios repeatedly with a ‘reward’ given for successes, often a score increase.

Two classic games from the 80s – Montezuma’s Revenge and Pitfall! – have thus far been immune to a traditional reinforcement learning approach. This is because they have little in the way of notable rewards until later in the games.

Applying traditional reinforcement learning typically results in a failure to progress out the first room in Montezuma’s Revenge, while in Pitfall! it fails completely.

One way researchers have attempted to provide the necessary rewards to incentivise the AI is by adding them in for exploration, what’s called ‘intrinsic motivation’. However, this approach has shortcomings.

“We hypothesize that a major weakness of current intrinsic motivation algorithms is detachment,” wrote Uber’s researchers. “Wherein the algorithms forget about promising areas they have visited, meaning they do not return to them to see if they lead to new states.”

Uber’s AI research team in San Francisco developed a new type of reinforcement learning to overcome the challenge.

The researchers call their approach ‘Go-Explore’ whereby the AI will return to a previous task or area to assess whether it yields a better result. Supplementing with human knowledge to guide it towards notable areas sped up its progress dramatically.

If nothing else, the research provides some comfort us feeble humans are not yet fully redundant and the best results will be attained by working hand-in-binary with our virtual overlords.
