Probably my favourite porn parody Sci-Fi AVN. I like even more, some others Sci-Fi games with humour and which have parody moments; but while of course all AVN have sexual content, beside this one none of my top have so many and are so concentrated on them or have so much nudity (in SpaceCorps XXX nudity is almost constant and sex scenes are one after another). Usually I prefer AVN more focus on the plot and characters, with maybe erotica stylistic but less sex; yet I appreciate the originality and unpredictability of this game, plus it is hilarious with a lot of very dark humour in my taste. It is so ridiculous that although being a porn parody, it is hard to predict what will happen next.
Generally it looks nice (the eyes of especially Cis are the best eyes I have seen in AVN) and it has an outstanding soundtrack (probably my second favourite, but the first one was just more in my music taste, while this one have more mix of genres). There aren't many animations, but some scenes where it just uses montage of images with music are great examples of how to embrace this specific form.
Because it is so concentrated on porn, I feel it is needed also to appreciate the huge variety in that aspect (which is optional depending on the preferences). I personally have skipped male with male sexual interactions, so have missed part of the content, but sometimes instead of just missing the scene - there is an alternative one and from the descriptions of updates I suppose that all intersexual threesomes if you are OK with them are available yet differ depending on your previously established orientation. To see all scenes, you will have to be very open-minded pansexual, but you can enjoy it as hetero or homosexual too (at least if you just prefer not to see different orientation's sex, but aren't repulsed by seeing many nude bodies of different genders and among them various body types). You like thin, round or muscular ladies - you have it, you like thin or muscular men - you have it too, as well as some futas if you want, plus many more weird looking aliens of all genders.
PS Although characters aren't very deeply written and are rather the mix of clichés (what suits to parody), yet as with the appearances there is a big variety of personalities too and you can find some which you like in that aspect too.
