How you (yes, you) can benefit from 1-on-1 synchronous playtesting

One-on-one synchronous playtesting is being pushed as a serious tool for teams that want clearer feedback with less noise. Brian Cronin will present the case at the 2026 GDC Festival of Gaming, focusing on why direct, live sessions can reveal player confusion, friction, and intent in a way that surveys or passive telemetry often miss.

The appeal is straightforward: a single tester and a developer in the same session can turn vague reactions into actionable observations immediately. That makes it easier to probe why a player hesitated, what they misunderstood, and which systems are doing too much work behind the scenes. For smaller teams, it can also be a cheaper, faster way to validate changes before committing to broader testing.

The practical value is in iteration speed. Designers can watch moment-to-moment behavior, ask follow-up questions, and adjust onboarding, UI, pacing, or encounter structure with less guesswork. It’s especially useful when a game’s core loop is still shifting and the team needs qualitative insight more than aggregate data.

The broader takeaway is that playtesting doesn’t have to be a big, formal operation to be useful. For teams willing to sit in the room and listen closely, synchronous one-on-one sessions can expose issues that get buried in larger groups, while still fitting into a production schedule.
