* NetHack
Scores in NetHack grow without limit.
For every killed monster the player gets the same number of points.
For regular monsters this is not really a problem as after a specific number of kills these monsters won't be generated again.
Unique monsters like the Wizard of Yendor or the riders can be killed infinite times.
* UnNetHack
In UnNetHack the score points per monster kill are decoupled from the experience points and decrease continuously with every kill.
For the first kill, the complete points are awarded, the second kill yields only half points, the third kill only a third, etc.
