Assassin's Creed: Brotherhood has a larger, single contiguous map.
| Game | Primary Locations | Structure |
|---|---|---|
| AC II | Florence, Venice, Monteriggioni, Forlì, San Gimignano | Separate city maps loaded individually |
| Brotherhood | Rome (entire city + Vatican), plus smaller Tuscan areas | One massive open world (~3x AC II's combined land area) |
Brotherhood's Rome is denser with activities (shops, factions, collectibles, Borgia towers). AC II offers more variety in distinct city aesthetics.
