That depends what you need. It's possible to track different measures in a game, for instance:

• eye tracking to show where they focussed their attention
• time/speed through the game
• total points
• player errors
• time on specific areas indicating confusion or difficulty

etc.

Are you looking for someone else's data or to collect your own? And what engine are you using if you are collecting your own?

Thank you for your answer. I am looking for someone else's data.

I'm not aware of pubic data of that kind. I'd try looking for a research paper that has collected the kind of data you want and just ask the researchers for a copy of their data.
