Real-life historic battles are going to feel epic
The Battle of Bunker Hill is just one of the many historic events you'll get to witness in Assassin's Creed 3. Others could include the Great Fire of New York in 1776 and George Washington's famous Crossing of the Delaware.
If the portrayal of Bunker Hill is any indication—the game brought the battle to life better than any book or movie I've ever seen—history buffs are going to be in for a treat. Even if the presence of an assassin at those events might not be historically accurate.
