Tony Hawk's Pro Skater 4 revolutionized the series with its open-ended career mode, allowing players to explore vast levels freely while tackling goals and challenges at their own pace. The expanded trick system offered deeper combos, and the quirky side missions added a healthy dose of humor and variety. However, difficulty spikes and occasional frustrating goals can slightly dampen the experience. Still, Tony Hawk's Pro Skater 4 remains a beloved entry, pushing the franchise forward with its ambitious level design and focus on player freedom.
