Well, I guess I'll be the curmudgeon here. Eye candy aside (like guys flying through the air from cannon hits), that "sail combat" looked pretty bad to me. Too many ships moving in improbable directions for square-riggers, like battle lines passing each other at 180 degree opposite angles. Too many ships "fighting" with furled sails.

Maybe the wind and sailing mechanics will be more realistic in the final release, and they're just showing this because the eye candy is running ahead of the sail combat engine. If the tactical maneuver isn't realistic, then I don't know why they'd bother doing a naval combat engine at all? I hope they're not dumbing this down, thinking that people can't figure out how sailing works....
