Yet it's clear that games like DCSS (and even TOME) are much tighter than Angband. It's easy to be tight with an RPG, it's harder with a roguelike.

Most games today are "tight" meaning that the game progresses you along at a constant pace and throws appropriate challenges at all steps. It comes from a mindset that the player will always choose the most boring way to progress possible, so you need to force the player into difficult scenarios. This is the number one complaint and it's a bit of an annoying one. I'll discuss a few of them and try to explain why they are why they are from my point of view.ฤก) Slow pace/grind. Some are design decisions, some are historical, some are accidental (and could be changed). I think a lot of the commenters hit on some of the key points. (old-timers might recognize my user name)
#ANGBAND DIG CODE#
I used to play angband a lot, and even wrote some code for it back in the day. It's an entire grad level course to cover the basics, to be honest. There are lots of other things that can happen. You can also get different kind of scattering, like Thomson scattering (used in experiments to measuring densities and temperatures), Mie scattering (off of larger bodies in dusty plasmas).

Super dense bodies act like blackbodies due to this behavior. It takes ages for light to propagate from the center of the sun to the corona due to it being constantly reemitted. If the plasma is dense enough (optically thick) light can be absorbed and reemitted over and over again. Other waves pass through almost entirely unaffected, accept by the standard slowing down of light passing through matter. This is similar to Landau damping, which is often used in current drive applications. You can also get other forms of absorption, like the kind of absorption picked up by a surfer on an ocean wave. This is a common heating in experiments, and it's done with both ions (ion cyclotron resonance heating) and electrons (electron cyclotron resonance heating). Commonly this occurs if the wave is a multiple of the frequency that particles are gyrating around the magnetic field. Some waves can propagate and be strongly absorbed. This is also how radio waves reflect off the ionosphere and are able to reach your receiver quite far from the antenna. A common reflection is due to the plasma density, so if you know what density the wave reflects at (calculable) you can launch a wave and determine at what distance from the antenna the plasma reaches that density. Some waves cannot propagate and get reflected. It depends on a lot of things, the frequency of the wave, the density of the plasma, the strength of the magnetic field, the polarization of the wave, and the direction of propagation with respect to the magnetic field. It turns out you also get a frequency shift in the scattered light because the electrons have a significant velocity, this frequency shift can be measured giving information about the temperature of the electrons. In this case the scattered light can be re-emitted in any direction (hence the scattering part).
#ANGBAND DIG FREE#
In this case light interacts with a free electron which absorbs and then re-emits the light. Just as an example, consider Thomson scattering. For frequencies that can propagate unimpeded, the plasma also has a non-zero index of refraction which slows the group velocity of the light. How much the light slows down is given by the index of refraction of the material. These electrons can absorb and re-emit the light, with a net effect of the light being slowed down as it transits. The light is an oscillating electric and magnetic field, and the electrons in the glass also feel an oscillating field. Consider the passage of light through glass.
