The Long Game focuses on a familiar theme: the question of collaboration and making deals with the colonizer for "long term" gains.  I found the alien worldbuilding compelling and I appreciated the POV of Narr the slug-like 'alien' (though here it is humans who are alien, having come from elsewhere); however, I don't know that the theme could really be done much justice in this short of a format.
