Mobile testing is inherently complex. Unlike desktop experiences, mobile products travel with their users through a vast array of environments: From a packed subway car to a brief five-minute break at the office, or even an intense, focused session at home on your couch. Playing in the metro, on your couch, or when you are waiting for your doctor’s appointment drastically changes the experience that you will have with your game.

Do you believe in love at first sight? At Game Changr, we believe in Love at "First Time User Experience"! Think of your favorite Rom Com. Romance never start by exchanging resumes or handing each other a manual! We believe your first 10 minutes shouldn't be a tutorial. They should be a promise "This is who we are.

After a long discussion about the best time to start playtesting with a former Ubisoft colleague, I decided to post a previous Linkedin post regarding the topic. I recently come across an old video of MGMT’s first live performance from 2003 and it got me thinking. If you haven’t seen it, here is the link : It’s raw, goofy, and probably not ready for public consumption by today’s standards.

The new approach was systematic. They started with ability, making the behaviour as easy as possible. Then they aligned motivation with the actual experience. Finally, they designed prompts that matched the situation. Behaviour = Motivation × Ability × Prompt

Bruce Lee once said that "Simplicity is your key to brillance"; And Fogg's model is really simple : Behaviour = Motivation × Ability × Prompt

SDT About a decade ago, while moderating creative workshops at Ubisoft, I was introduced to Self-Determination Theory (SDT) , a psychological framework developed by Edward Deci and Richard Ryan. Though it wasn’t created for games, its insights into why humans stay motivated proved invaluable for helping teams refine their designs throughout development. SDT emerged from decades of research on what drives genuine engagement. Instead of focusing on rewards or punishment, it loo

Most studios DO test. They just test too late, with the wrong players, asking the wrong questions, and often ignore what those sessions truly reveal.

The recent Jaguar "Copy Nothing" campaign has sparked much discussion, unfortunately for the wrong reasons.
