is the writing better for tainted space? I was thinking of trying it out.
Its simutaniously more consistent in the kind of character Steele is (despite being able to choose between 3 different personalities), more reactive to what you do to your body and the overly blase attitude the majority of the people in it have to anything but sex feels like it makes a lot more sense than it does in CoC2 where there's supposed to be a fairly large demon invasion going caused by a woman who you can access via the same teleportation system you use to get around the world.
Outside of this reactivity/consistence I wouldn't particularly call it better or good though. Its got some really weird tonal shifts (gastigoff being the most infamous, but there's also the Myr planet and their actual life-long sex slaves and the pirate base you take over yet somehow can't do anything about, among other things, the drugged up slave orgy pit (except go in their and fuck them until they're actually hoping you get tired and stop)).
TiTs for the most part is happy to just be a place to for people to place their furry, futa, furry futa or whatever OC's, make content with them, without it affecting the world and it works very well because its set in a galaxy.
While when they do the same thing in CoC it both often feels stupid like Manticores having hundreds of sex slaves each despite being a low-level enemy when the demons are supposed to be the big threat (in tits you could just have a planet of manticores and this wouldn't be too weird) or the authors are very prone to write the MC however they want them to rather than writing a specific character (ie steele) reacting to events. CoC2 mc doesn't really seem to have any defined static personality and will randomly switch the way they speak and react to events from scene to scene and it can be really jarring.
TiTs is by far my favorite of the three games but its a game you play purely to go around fucking things, not to be the hero or anything. Almost everything that happens in it is incidental to the over-arching goal or straight up actually doesn't matter.
TiTs also has the authors justify stuff more. Ie you can become addicted to sucking someones cock, but its because their species has addictive semen with an actual mechanic, not because you clicked 'suck cock' 3 times and now you're automatically sucking it when you talk to them for no in-universe reason at all and the only out of universe one being 'because the author wanted the mc to react like that'
