The levels in Aggressive Inline are huge and the 2 minute timer used in the majority of games in this genre is now gone. You can skate around at your own pace until you start a time-based goal, this goal must be completed in the allocated time given. The only other thing you have to watch is your juice meter which acts as both a countdown timer and your special meter, as you land tricks your meter fills up. Standing around or bailing out causes your meter to slowly drain and if it drains completely the game ends. Keeping the meter filled isn't difficult though, so this is more like a formality than something you need to be careful of.

Aggressive Inline doesn't have rigid goal structures; each level has long lists of goals, including standard point and time-based goals, but most of the games goals are based on doing tricks on specific parts of the level. Like Dave Mirra 2, most of the goals are discovered when you talk to people within the level. You will probably find that completing most of the goals is easy, but you will also find a couple goals that seem far more difficult than the rest. When you complete goals you are rewarded with new levels. Each skater starts out with fairly weak stats in almost every category. You improve your stats by pulling certain moves. For example, if you want to improve your speed, you should skate fast, to improve your grind stats you will have to pull of some grinds or grind combos to up your stats. All other categories may be raised in the same manner.
