The campaign ends in 1800 even though an 1850 endpoint had been expected. Steamships and related technology in the game are the reason the later date seems more plausible. The resulting chronology problem belongs to Empire: Total War rather than to real technological history. Historical simulations can compress or mix technological periods in this way.

The game's steamship technology makes its 1800 endpoint seem inconsistent with the expected 1850 conclusion.
