What evidence in the leaks points to an RPG-like trait or stat system (for example, the +2% Focus from playing basketball)?
The leaks show Jason earning "+2% Focus" for sinking a basketball, explicitly suggesting numeric stat changes. The footage also displays on-screen icons when Jason attacks a driver that point to a morality or karma-like system, and a stamina meter for melee combat that drains differently with weapons, all of which support a more in-depth trait or RPG-style system.

What specific new UI elements for the Wanted Level were shown in the leaked GTA 6 clips (number of stars and police target icons)?
The Wanted Level UI shows six stars instead of the traditional five. The UI also displays police target icons indicating what the police are looking for, specifically icons for clothing, face, and vehicle. Answered
