It is worth noting that some exceptional games, despite scrubbing, remain large due to rich, uncompressed assets. For example, Fire Emblem: Radiant Dawn generally sits around ~3.2 GB even after scrubbing. Super Smash Bros. Brawl is notorious for its massive size (approaching 7-8 GB dual-layer) and will still be several gigabytes even after compression because of the massive video and music library.
