Besides manuals, Tony Hawk's Pro Skater 2 notably introduced cash rewards. Players earned money for completing career objectives, then spent it on progression and upgrades.
The cash system gave the sequel a stronger career structure than its predecessor. Profits could improve a skater's statistics, help obtain better equipment, and unlock additional levels and playable characters. Completing objectives therefore affected more than the score shown at the end of a run.
Manuals were another major addition, allowing players to balance on two wheels and link tricks into longer combinations. Together, manuals and cash rewards made the sequel feel more flexible and goal-driven while preserving the original game's fast arcade style.
Cash should not be confused with competition medals. Medal events still reward performance rankings, but the broader career economy is based on money earned from objectives and collected cash. Experience points and sponsor contracts are not the defining reward system introduced here.
