Trials in Tainted Space (TiTS) has proved itself to be a very divisive game as far as the indie porn game community is concerned. Whereas its predecessor, Corruption of Champions (CoC) had something to cater to almost any possible player, expanding as its development furthered, TiTS has if anything become more specialized over the course of its development.
If your one and only sexual interest is text-based furry futanari sex, perhaps with a hint of BDSM or the occasional man-on-man scene, TiTS is far and away your game. Almost every new update adds at least one new scene if not a wholly new futanari furry character to bang, with an occasional tweak to an RPG mechanic or minor addition to the main story. But if you're looking for literally any other fetish (incredibly sparsely represented fetishes include: vanilla heterosexual sex between a fully male partner and fully female partner, incest, and sex acts involving an NPC's penis that is smaller than eight inches long), you are basically out of luck.
Don't be fooled by promises of a paid writing staff and a dedicated community. The community's main goal at this point seems to be writing ever more specific furry futa 'waifus' for the various community members, and the writing staff largely does the same. It must be said that occasionally some of the writers, most commonly Savin, really do add to the diversity of fetishes represented with a high quality addition. But most updates? They add insert-random-Earth-or-sci-fi-species futa furry character or a new scene with a currently existing furry futa character about 95% of the time.
In other words: this is your holy grail if you love furry futas. If you're like me, however, try it maybe once a year and see whether or not you can fuck the main character's cousin yet in a scene with full sexual description that doesn't end the game. I'd wager the answer will remain 'no' until at least 2019.
To be honest, if this game truly billed itself as catering exclusively to a furry futa fetishist community I'd probably be giving it a four or five and simply lamenting that it isn't for me. As a game promising a wide range of content for all comers, however, I rate it according to how much I personally enjoy it.
Three stars.
Decent RPG mechanics, but difficult masturbation material for all but very specific fetishists.
