Unlike most adult IF, Softporn Adventure has actual puzzles and gameplay outside of simple seduction. Given the era, it's not surprising that the puzzles are simple and shallow and the prose is flat.
But no one talks about this game to talk about it. There's the sleazy and unpleasant story behind the game's cover. There are the bizarre and illogical puzzles. And, of course, this game would later be reworked into Leisure Suit Larry, and the irony that there's actually a worse version of Leisure Suit Larry.
In a strange way I kind of wish this had been a Hi-Res Adventure like The Wizard and the Princess or Mission Asteroid. Not because it would be hotter with pictures (nothing could make this material erotic) but because I have a morbid interest in seeing how this game would look in that "crude even for the Apple ][+" style.
Anyway, as a game, Softporn Adventure alternates between simple, boring puzzles and parser-wrestling nightmares. It doesn't have much to offer even for its era.
... assuming you have a thing for Deanna Troi from Star Trek: The Next Generation.
you're dropped into the uniform of William T. Riker and the quarters of Deanna Troi. (it's not clear whether this is happening before NextGen or after Star Trek: Insurrection, because they were never a couple during the series' actual run.) within very short order, you will also be dropping said uniform and, ah, initiating docking procedures, so to speak.
the main thing that distinguishes Deanna from other works of adult IF is that it gives Deanna agency and active participation. most works of AIF present one's prospective partners with all the detail and implementation depth of the wrench in Zork I: the item is there for a purpose, it doesn't particularly matter what it looks like, and until you start applying verbs to it it's not going to do anything, either.
in other words, this feels like a sexual fantasy, while most AIF feels, at best, like a still photograph.
now, i did still have trouble with it, but that's probably because i'm not personally well-versed in how to use the implement Commander Riker will be relying on. but it was still fun reading the dialogue, which rings remarkably true, and exploring the various Trekkian room features.
i'm still not sure parser is the best way to go with AIF -- it's always going to be somewhat on rails, and using Twine would save the player some verb guessing and the like. but honestly, this is a short erotic story where no one's being manipulated or taken advantage of and two consenting people get their nookie on. that's worth celebrating.
i can understand the desire of art to be transgressive, and that this piece is intended to start as erotica before abruptly diving deep into what is, to me at least, (Spoiler - click to show)serial-killer horror.
i realize that (Spoiler - click to show)vore is a known fetish, it has its adherents, i've had furry friends who were into it, Your Kink Is Not My Kink But Your Kink Is OK As Long As It Only Remains A Fantasy.
but as something to spring on a reader without any warning, in a game presented as ordinary porn, it's a little on the extreme side.
if the (Spoiler - click to show)serial killer stuff had been accurately signposted in advance, i would probably have given this game four stars ... from another room ... using a long pole to click the mouse. it's very well written. but the fact that this incredibly triggering content was provided without warning forces me to reduce the rating considerably.
one of the problems with IF erotica is that it's generally written in a vacuum. minimal descriptions of anything but sexual acts, shallow implementation in general, and heaping helpings of read-the-author's-mind. even when the writing per se is good (e.g., Deanna) there's an inherent feeling of artificiality; much like bad porn, it just kind of starts at the sex and ends after it.
in order for an erotica game to work for me, at least, i have to understand what the characters are like, how they feel about each other, and what this means for them. to put it another way, i need the backstory.
(i acknowledge that there are some people who do prefer their porn to be storyless and characterless. to this, i reply that they are free to howl "get on with it" at my kind of erotica, just like i'm free to be bored and mildly revolted by theirs.)
"And the Robot Horse You Rode In On" is unapologetically a work of erotica; the author has even acknowledged that it began with a mental image of (spoilered for sexual terminology) (Spoiler - click to show)predicament bondage and expanded from there.
but for a work so short, it does an excellent job of characterbuilding and worldbuilding. you can understand your character. you can understand the other character. you can understand how this arose and where it might go.
well-written, engaging, and very, very hot.
