Description:

Subsequent playthroughs through a game can become repetitive if the player experiences the same mechanics and progression each time. One solution to add variety and uniqueness to each playthrough is to introduce players to an expansive skill tree with unique and meaningful abilities where players can unlock distinct abilities or weapons, encouraging experimentation and different builds or playstyles on subsequent playthroughs.
