There's one scene in the original campaign that I wish could've been done slightly differently: When Arkantos kills Kamos

If you looked at some of the flavor text for Arkantos and Kamos, you'd know that Kamos killed Arkantos' wife before the events of the game. As such, during the scene where Arkantos kills the Minotaur pirate, he should've made mention of his wife and of avenging her death.

It would've made a load of sense, and would've added to Arkantos' character.

Oh well, way too late now.
