Journey Down has an interesting premise: take an adventure game (a somewhat comedic one, although it doesn't look it that much) steeped in tribal African culture and force its protagonists down and out of the influence of civilized society and into something wholly different (hence the "Journey Down). This might be worth it for interesting cultural implications alone, but it's hard to say since it's merely the first chapter of something more involved. Either way, a Telltale-esque title for $3 is a good deal.
