Aggressive Inline
Combine the many tricks and styles of the extreme sport of inline skating with a Tony Hawk-style system, complete with targets and huge arenas, and you have Aggressive Inline. In career mode, you'll have to complete objectives (such as grind a specific object to jump over large gaps and earn points) to unlock more arenas. There are 7 arenas in total, and if you get bored with these, you can create your own in the park editor. The game doesn't use a hard time limit, but the so-called "juice meter": it fills up when you perform stunts, and when it gets empty, the level ends. During the game you increase your character in seven stats, such as speed and grinds. The game uses a "learning by doing" approach, that is, the value improves if you perform the corresponding actions often enough. In each level there are also five hidden keys that open new areas within the level.
