I've come to realise something in the process of playing Avernum: Escape from the Pit - the latest in a long line of releases from the tiny development house Spiderweb Software. Imagination is an incredibly powerful tool. The more limited the graphics, the more sparse the sound effects, the further your own imagination can take you. It is something disappearing from the gaming world as they enter the realm of fully realised and realistic 3d worlds and unending reams of voice acted scripts. And, perhaps that is a shame.
