Going the distance
to build games
people love.

Player support in Brighton. Marketing in Taipei and Moscow. A studio of my own in Limassol. These are the field notes — the calls I’m proud of, the ones I’m still not sure about, and the math underneath both.

01Field notes

Short, honest dispatches from twenty years of building. New ones get added as the building allows. Filter by what you came for.

Hard calls2023

Decisive ≠ correct

Two doors, five months, and a call I still can't grade.

When the traffic model broke I had two doors. One: lay off most of the team and pivot to burst-session mechanics we had no experience in and no appetite for. Two: reuse the engine, reskin Rome to Sengoku Japan, move to a leaner model, and move fast. We greenlit Daisho on 23 January 2023 and shipped it that June — concept to live in five months. It kept the team whole. Whether it beat handing the rest of the money back to investors, I still can’t tell you.

Takeaway

You can commit fully, move fast, and still not know for years whether you were right.

Growth & ASO2023

Free traffic is a loan the platform can call

The day your free channel turns paid is already scheduled.

Early 2023, Google Play swapped most of its organic auto-collections for ad inventory. To a player the home page looked identical; to us, free traffic had silently become paid traffic. A low-LTV player from Vietnam covers his keep against staff and servers — bolt a CPI onto his head and he’s a hole in the P&L.

Takeaway

Your unit economics live on someone else's platform. Model the day the free channel turns paid, because that day is coming whether you're invited or not.

War stories2022

February 2022

We shipped Gladiators on the 22nd. On the 24th, the war started. My team was in Russia and Ukraine — both sides of the line, inside one company, fresh out of two years of COVID with travel still broken. The work for the next several months wasn’t game development. It was relocation logistics, conscription risk, and keeping people who suddenly had every reason to resent each other from doing so across a video call.

Leadership

In four years — through a war and a round of layoffs the market forced on me — two people left because they chose to. One for a childhood dream of London and a visa a Cypriot company couldn’t sponsor. One to start a family.

Money2022

I turned down sixty million

The strongest round can be the one you don't take.

The launch went well enough that I could have raised again at a $60M valuation. I passed — we had cash in the bank, inflation was high, and I wanted to build, not dilute. Months later the ad market turned and the number would never come back. I’d make the same call and I’d lose sleep over it again.

Takeaway

A term sheet is a price on your optionality, not a trophy. Read it as the cost of the round you didn't run.

Growth & ASO2016

Find the niche nobody's defending

Moscow, a doomed MOBA, and a budget that got pulled.

My first real touch with mobile was a MOBA that couldn’t pay for itself. Marketing budgets were pulled, so I had to learn organic growth or watch it die. That necessity became the method: one proven survival-RPG template, reskinned into settings the big spenders find too small to bother with — Rome, then Sengoku Japan, then the Viking north.

Takeaway

When you can't win on budget, win on the niche your competitors think is too small to defend.

02The work

One studio, one proven template, three worlds. Plus twenty years of getting there.

03Now

The newest bet is PromptSurge.me — helping app and game developers turn user-review sentiment into organic traffic. The same instinct as everything else here: when you can’t outspend, out-think. Meanwhile Colossi keeps shipping — Vinland Tales live, Gladiators alive. The honest position: a profitable indie studio in a shifting market, not a rocket ship and not pretending to be one.

An open invitation

Daisho is parked, and it’s waiting for the right person.

It converts to install better than anything I’ve built, and it’s sitting still because it needs a game designer with real vision for mobile RPGs — someone who wants to build, not decorate. If that’s you, there’s a studio and a converting game behind the offer, not just a job. Let’s talk.
