Ok, there's the <i>Mist</i> Modification (HL2 mod), but what about having a Myth (or Myth II) mod? What if Land Battles were replaced with (an optional) Myth II battle or exploration? Now that I think about it, wasn't there a Myth II pirate plugin at some point called <i>Pirate's Life for Me</i>? This, in tandem with additional mission material, could seriously widen the possibilities, methinks.
