Building a Marketability-First Design Process

A marketability-first process tests whether people will click on the game before you build it. The test is cheap, fast, and filters out concepts that would fail commercially regardless of quality. Building it into your design process rather than running it after production means you only build games that have already passed their first commercial test.

Why marketability comes before production

The most common failure in mobile games is building a good game that nobody discovers. The quality is fine. The retention is fine. The install cost is too high, which means every player costs more to acquire than they return.

Marketability testing answers one question early: can this concept attract clicks at a reasonable cost? If it cannot, no amount of production quality fixes the problem.

This does not mean marketability is the only thing that matters. It means it is the first thing that should be tested, because it is the cheapest test and it gates the most expensive work.

Test whether people want to see it before you build it. That order saves months.

What marketability testing actually looks like

A marketability test is a small ad campaign that measures interest in the concept before the game exists.

The components are simple.

1. A visual hook. One image or short video that communicates the core experience in two seconds.
2. A campaign. A small budget (typically 100 to 300 dollars) run across two to three audience segments.
3. A landing page or store listing. Something to click through to, which measures conversion after the initial click.

What you measure:

• Click-through rate (CTR). Did people want to see more? This is the primary signal.
• Cost per install (CPI) or cost per click. How expensive is this audience to reach?
• Creative performance by variant. Which visual hook works best?

The whole process takes three to five days and costs less than a week of development. It answers a question that otherwise waits until launch.

Choosing concepts that test well

Not every game concept produces a strong visual hook, and that is useful information.

Concepts that tend to test well share three characteristics.

Instant readability. The core action is visible and understood in a still image. Stacking, merging, building, and destruction all read clearly. Complex strategy and deep narrative do not.

Visual contrast. The screen looks different from everything else in the ad feed. Bold colours, unusual scale, or a striking transformation catch the eye.

Curiosity gap. The image raises a question the viewer wants answered. A half-finished structure, a choice between two options, or a before-and-after comparison all create this.

Three concept types that consistently struggle in marketability tests.

• Abstract or minimal art styles that do not stand out in a feed
• Games where the core action is invisible or internal (thinking, planning, managing)
• Concepts that require explanation to understand

This does not mean those games are bad. It means they need a different acquisition strategy, and the marketability test will tell you that before you build them.

Building the test into your process

The test belongs between concept and production, not after production.

A process with marketability built in has four stages.

The marketability test kills most concepts, and that is the point. Three out of five concepts will not clear the bar, and you want to know that before spending weeks on a prototype.

The prototype build starts only after the concept passes the marketability test. This means you never prototype a concept that has already failed its first commercial test.

Reading the results honestly

Two traps in interpreting marketability data.

Optimising for CTR alone. A misleading creative can produce a high CTR and terrible retention. The ad promises something the game does not deliver, and players leave immediately. CTR should be high, but the creative must represent the actual game.

Moving the bar. If you set a CPI target of two dollars and the test comes back at three, the result is a fail. The temptation is to raise the bar, because the concept is exciting and the gap feels small. But a three-dollar CPI in a controlled test typically becomes a four or five-dollar CPI at scale, and the gap grows.

The discipline is to set the bar before the test and hold it after. Concepts that narrowly miss deserve a creative revision and a retest, not a pass.

If a concept fails twice with different creatives, it is the concept. Move on, per When to Kill a Game and What to Salvage.

Creative testing after the concept passes

Once a concept clears the marketability bar, creative testing continues through production. Each new creative variant is a data point about how to market the game at launch.

Three creative tests worth running during development.

• Art style variants. The same concept with different visual treatments. A cartoon version versus a realistic one may have significantly different CPIs.
• Hook variants. Different moments from the game as the opening frame. The build action versus the destruction action versus the reward moment.
• Format variants. Static image versus short video versus playable ad. Each format reaches different audience segments at different costs.

By the time the game launches, you have a library of tested creatives and a clear picture of which audiences respond at which cost. This is a substantial advantage over launching with untested creatives and hoping.

What we would do

Generate five concepts in a single session. Spend half a day sketching the visual hook for each. Run a three-day marketability test for the top three.

Build the prototype only for the concept with the strongest CPI below your target. If none clear the bar, generate five more concepts and test again. The cost of another test round is days. The cost of building the wrong game is months.

Continue creative testing during production so launch day has a proven creative library ready. The game and its marketing develop in parallel, and neither waits for the other.

The short version

• Marketability testing answers whether people will click before you build the game.
• A test costs 100 to 300 dollars, takes three to five days, and filters out concepts that would fail commercially.
• Good concepts have instant readability, visual contrast, and a curiosity gap.
• Place the test between concept and prototype, never after production.
• Set the CPI bar before the test and hold it after. Moving the bar is the most common mistake.
• Continue creative testing during development to build a proven library for launch.
