Case studies with the numbers left in
Eight projects, four published under their real names. Metacritic 63 on Switch, 650,000 downloads on a crossplay VR shooter, 52,000 concurrent players at 62 ms, $2.4M in first-month marketplace volume, 87% less manual processing — each with the constraint it was built against and the measurement it was judged by.
The four named projects. Screenshots from the games’ own store listings: King’s Bounty II — 1C Entertainment / Prime Matter (Nintendo eShop); X8 — Thirdverse (Steam); Metarun — Encore Games (Google Play). ArendaOS is our own product, rendered from its live markup.
Featured case studies
Eight examples of the kind of delivery work Yarvixo handles. Four are named — King's Bounty II, a retail console game you can buy today; X8, a free VR shooter live on three storefronts; Metarun, a client game named with permission; and ArendaOS, our own product. The other four are anonymised: three are client work, and one describes three local businesses of our own, unnamed by choice. X8 is the one where the storefronts credit the publisher rather than us, and its own page opens by saying so.
King's Bounty II — Nintendo Switch Port
A named retail console title, on sale in the eShop: a 7 GB Unreal Engine 4 open world moved onto a 4 GB handheld, from 6–8 fps to a 30 fps target, shipped day and date with PC, PS4 and Xbox One.

A named client game, free on Steam, Meta Quest and Pico: every engineering system in an Unreal Engine 5 5v5 VR shooter where a standalone headset and a GTX 1080 share one match. Four engineers, eighteen months — the design, art and rendering were the client's.
