A simple thing you can do for outdoor scenes is:

Directional Bumpmapping + ShadowMap (sunlight) +
Skylight (bumped cubic lookup or interpolation between sky/ground color based on per-pixel normal)

The skylight gives you some ambient with color variance based on the per-pixel normals so you get lighting variation even if the sunlight is weak or in shadow and you can always see the bumpmapping effect.

This is why I think that HL2''s engine is superior, it looks like it can support more than an extremely dark corridor.

All the world lighting in HL2 precalculated gi. With Doom it''s all real time direct illumination. Both these engines were geared towards first generation dot3 hardware as a minimum, so either tradeoff is acceptable.
