It's one thing to define a genre with an excellent game, but it's another thing altogether to produce a game series that continues to be the best in that genre year after year. Yet ever since the first release, the Tony Hawk's Pro Skater series of games continues to be the crowning jewel of the alternative sports genre and is the measure by which all other games in this genre are judged. The fourth installment in the series is no exception. The revised career mode, challenging goals, enormous and well-designed levels, and extended trick system all make the gameplay of Tony Hawk's Pro Skater 4 top-notch, and the depth and breadth of things you can accomplish in the game ensure that it will be a game you'll be coming back to for some time. Fantastic sound, fluid animation, outstanding graphics, and a well-rounded soundtrack help smooth out the finished product, while a lengthy list of tricks and the ease with which you can execute them will pull you deeply into this game and keep you there. It's this level of attention to detail, in concert with the ability to make it all one seamless, cohesive experience, that makes Tony Hawk's Pro Skater 4 our Best Alternative Sports Game on Xbox.
