If you haven't seen Sword of the Stranger and you like samurai ronin stuffz you should watch it, it has the best sword fights I've ever seen.
List in no particular order:
Afro Samurai
Sword of the Stranger
Ninja Scroll
Baccano! (Awesome 1930s mobster anime)
Appleseed was pretty cool, so was Spriggan (pretty much the same shit).
I liked Berserk, but the ending was a major disappointment.
In my opinion, if you play Mount & Blade and like anime, you should watch Berserk. It is pretty much an anime version of M&B with some added drama.
