It was far too dark for my taste, especially in the first part, and the part I personally liked most was the Imp Town.

I played it through, though, and considering the mechanics alone, I didn't see it as a bad game at all - it was just the setting which never quite liked.

I still do hope that the Ranaar will return into the series at one point.

They had released a promotional game called "Imprunner" at one point : http://www.larian.com/riftrunner/imprunnermirrors.php
