Slow and plodding? Sounds like a misinterpretation of deliberate and tactical to me. Unless I'm thinking of a different eighteenth century.
Edit: I'd also like to point out that classical battles involved huge amounts of men generally shoving against each other for the better part of the day with relatively few casualties, except for the side that broke, and even then the majority would escape. Despite that RTW was a game that to me might not have been a prefect representation of the era, but by and large felt right. Cinematic liberties are necessary for a game if battles are to have defining moments and have the player feel like he's in charge.
