I have a lot of sympathy for the Troika roleplaying game even though I don't think anyone really knows what it is exactly, other than an equal parts absurd and surreal exploration of the OSR trend. Still, Between the Skies seems to me to be exactly in that vein, offering mainly a big bunch of random tables linked together with the promise of a malleable space opera setting on hallucinogens, the kind of game where you can play as a swarm of mutant bees aboard their flesh-cloud shaped ship. If this description, and the prospect of playing very narrative games (actually leaning more on the side of FKR) doesn't scare you, reading this game - free! - may interest you.
Thanks for the very insightful comment, Côme! Troika! was certainly a big reference point for me - and I would say 'you can play as a swarm of mutant bees aboard their flesh-cloud shaped ship' is a pretty good summation of one of my design goals :)
I hope that BtS will serve as a good resource for players like me who like Troika! and 1) prefer FKR/ultralight play and 2) would like some extensive procedures/tables for developing and exploring their own weird worlds. I should note, I've also included a set of procedures for using Troika! backgrounds and converting them to be used alongside other BtS PCs (p. 39–40).
