If any player intends to have some level of success, they probably need to read the game manual.
Potential: While all players can improve their skills with training, not all have the ability to become superstars. Potential acts as a soft cap on player skill. When the player's skills reach the maximum their potential will allow, their training will slow down considerably, but will not become zero
Seems pretty straight forward to me.
Yeah nobody reads a game manual unless you force them to, or incentivize it.
Like, "Read the game manual, pass a quiz on it, and get 50K" Then people would read it.
