Deanna

... 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.
