Hyper Hippo's Denault on AdVenture Capitalist rewrite
Alexandre Denault, VP of production and technology at Hyper Hippo Entertainment, discusses the 2022 ground-up rewrite of the idle hit AdVenture Capitalist. The decision was driven by a tangled codebase where even simple changes caused unexpected issues, effectively stalling feature development. Despite the cost, leadership supported the rewrite due to the game's long-term potential. Key challenges included missing documentation, which forced teams to reverse-engineer decisions, and preserving player progress across save formats. Bugs that players had come to rely on were treated as expected behavior, making fixes risky. The team successfully migrated all player data, and the game has continued to receive updates, including progression revamps and new features. Denault notes that an incremental rewrite would have taken twice as long, and the decisive action has paid off.
The article provides a case study on a game codebase rewrite, relevant for game developers and those interested in engineering decisions, but it does not directly impact the advertising technology industry.

Anthropic Updates Claude Code to Block Game Cloning
Anthropic has updated its AI coding tool Claude Code to prohibit the recreation of existing video games, even under different names, to protect intellectual property and address concerns from indie developers about AI-generated clones. The change, pushed on October 27 and internally named 'tengu_heron_brook', cannot be disabled by users and instructs the model to build only original games, genre games, or games from the user's own designs. Anthropic's Addy Osmani confirmed the update but acknowledged that it has over-blocked legitimate reverse engineering and unrelated tasks like analyzing Windows crashes. Experts question its effectiveness due to potential prompt bypasses and the impossibility of verifying asset ownership. The update follows incidents like Digital Sun Games cancelling a playtest for ReVamp and Valve facing pressure over AI-made clones on Steam. Osmani stated the company will adjust the rules to strike a balance.
AdHoc Studio Celebrates Dispatch Anniversary, Reflects on Chaotic Development
AdHoc Studio marks the one-year anniversary of Dispatch, a narrative adventure game that became a surprise hit in 2025. The game has been played by over 5 million people. To celebrate, the studio is adding a commentary and storyboard mode to the deluxe edition, releasing a soundtrack vinyl and book, hosting a concert in Los Angeles on December 3, and launching the game on mobile on December 9. CEO Michael Choung discussed the chaotic development process, including learning self-publishing and dealing with console certification, which was 'crushing'. The studio initially struggled to find a publisher and was dropped by one, but secured finishing funds from Critical Role and other partners. Choung attributes the game's success to compelling characters and streamer-friendly design, which helped it gain traction on Steam. Looking ahead, AdHoc plans to continue episodic releases and is exploring film/TV adaptations of Dispatch.
Epic's Ari Arnbjörnsson Reveals AAA Development Realities
Ari Arnbjörnsson, senior software engineer in developer relations at Epic Games, described the messy, highly specialised, and human realities of triple-A game development in a Pocket Gamer Connects Helsinki session. He said studios operate on a normal distribution of skill, shipped titles often contain legacy scaffolding and quick fixes, and internationalisation is a complex challenge (right-to-left UI, pluralisation, cultural content rules). Arnbjörnsson also noted deep role specialisation at AAA firms and that knowledge-sharing has improved, though large studios retain advantages such as pro support and direct escalation contacts with platform holders.
