And, what lighting does Half Life use? Lightmaps? And what about Unreal and Unreal Tournament?

They all use lightmaps for static object (like the entire level) and usually OpenGL lights for dynamic objects like players and items.
Although I think dynamic lights may be done with a projected texture when applied to the static level, as the tesselation is much lower than on dynamic models.

Regular GL lights are still pretty good. You get them practically for free, so they''re great for avoiding doing lots of extra calculations yourself. Its just that you don''t get much flexibility.

Is ''Dynamic Lighting'' simply using OpenGL/Direct3D lights which move dynamically?

Dynamic lighting is a term used for any lighting that changes.

Quake/Unreal series games use a projected textures as the last guy said, that is blended with the lightmap for dynamic lights on lightmapped level gemometry. On characters, vertex lighting is used (OpenGL lighting).

I believe unreal uses vertex lighting for terrain maps and it definitely does for static meshes.
