[1] They have shown a propensity for re-releasing previously self-published games in professionally illustrated editions, having drawn multiple times from the catalogues of db-Spiele and, more recently, Winsome Games, and re-releasing those already published by themselves with a different theme and varying degrees of revision of the rules.
Alhambra has since spawned many expansions and a number of standalone spin-offs and could be considered the "franchise" of the company.
They are also known to some extent for publishing many games designed by Dirk Henn (and not only, though primarily, those previously self-published by him), with illustration by Jo Hartwig or Michael Menzel and/or with an Arabian theme, whether set within the Arabian Peninsula itself or an Islamic culture such as Al-Andalus.
In 2000, Queen Games switched from publishing their games in traditionally horizontal, shallow, rectangularly faced boxes in various shapes and sizes to using distinctively "fatter" boxes designed for being stacked vertically in only four standardised box sizes[3] and their publications from about 2005 to 2010 have typically been produced in both a domestic version with only German rules and an export version (recognisable by the flags indicating the included languages on the front of the box)[4] with rules in English, French, Spanish, Italian, Dutch and German and the title on the box changed to be more language-independent (such as Alhambra instead of Der Palast von Alhambra).
If the game components contain text this is replaced in the export version with either language-independent symbols (as has been the case with Alhambra and Roma) or a translation into English (as is the case with more recent releases such as Granada and Arena: Roma II).
