No 10: Full Confidence is not the only game based around Westminster’s wheeling and dealing.

Fantasy Parliament, external is a browser-based game designed by another UK-based developer, Evan Roberts, which lets players draft their own fantasy league of real-world MPs, scoring points based on their real-life media coverage.

With the strategy game’s Policy Tester, players can even type in proposals to a ChatGPT-style AI model, which then replies in the style of how it believes different groups of voters – such as Coastal Keith or Graduate Gemma – would react.

Meanwhile, UK Politics Simulator, “built on real UK data down to ward level”, is reportedly due out later this year for PC, made by the Scarborough-based company Black Cannon Games.

Despite the success of his own venture, currently ranking 5th in Apple’s UK paid games charts – above Monopoly Go – Brewis said he does not know if any politicians have actually played his game.

However, he has received some feedback on how accurately the game depicts UK political life, from his friends who work in the civil service.

“It’s exactly like this,” they told him, “but worse.”
