“Player Experience”, “User Research”, “Playtesting” are words that refer to the same aspect:
The study of how players interact with and experience games.

These studies are usually carried out by inviting voluntary participants in our offices in Milan, asking them to play one or more games, then collecting their opinions and comments on various features of the game. In order to involve as many people as possible, especially our fans and gamers from other countries, we are currently implementing online tools. Don’t hesitate to email to playtesting@milestone.it to receive information and updates on our future Player Experience International Program.
