Even battles in RTS games are sped up. Or do napoleonic battles take days sometimes (real days)?
Sorry, I'm just being pedantic
As for age of fighting sail, I keep seeing games that LOOK fantastic, and I wish they were built with the bones to make them realistic.
It needn't be painfully realistic, just realistic enough to simulate outcomes. All the stuff we see with fantasy sailing makes things like The Battle of the Nile impossible.
