Remaining Crackdown Achievements determined by observation
Realtime Worlds will be watching next week as you hit Crackdown's Pacific City for the first time, and for the weeks following. Shipping with only 900 Gamerscore points, the developer will decide how to implement the remaining 100 points by observing how players are interacting with their virtual sandbox.
It's not like Realtime has installed cameras into the game world; no, the developer will apparently gather most of its information by monitoring the most popular Achievements. If players are focused on unlocking the juggling Achievements, Realtime would likely up the ante with a new juggling-based challenge. But activities without existing Achievement tie-ins -- like building towers out of stacked objects -- might be harder for Realtime to observe (unless there's an internal stat-tracker we're not aware of...).
