Do different styles of combat require different combat mechanics? Or is it possible for a single game system to portray widely disparate forms of combat coherently and in a way that make them workable against one another?
Consider the following examples:
The question becomes, can a single combat system handle all those disparate types of combat? Should any single system be expected to be able to handle them adequately, or do different genres (or sub-genres) require unique combat systems? And, of course, the other question is, does the (A)D&D system handle them adequately as-is?
