i dont think 'most professional' is the right mark of distinction for this game, more like, highest originality/quality ratio.. theres no other scifi avn this good, for sure.
thats what makes this game stand out so brightly, it has no competittors in its category, and that category is in a genre that doesnt have a lot of categories to choose from. i mean you really got liek 3 categories to choose from when it comes to AVNs - you got "man moves back home", or theres "boy moves out of home", or that old chestnut "boy realises his sister is a bitch only cos shes horny for him".
with that background, "boy kidnaps co-worker and family and steals a spaceship to find kidnapped sister, then fucks them all, and some aliens" is a refreshing change. and its well written and rendered to boot!
