Rated version 2.05
I'm not quite sure why this is held in such a high regard by so many. Is it just the Mass Effect IP? I played for about an hour, so it might "get better 5 hours in". Also, 10 GB? Geez.
Gameplay:
I do not understand this need some AVN devs have to include sandbox or gameplay elements that aren't even worthy of the name. Either you go all in, build some complex and satisfying gameplay elements and build the game entirely on top of that or you make some (very) short and sweet standalone minigames before going for the lewds. This one is neither. Its gameplay is required to progress and it also features the ever so lovely "corruption" stat which you'll grind ever so slowly while encountering the same scenes over and over again. Granted, at least the grind is not as bad as some other games.
There's a repetetive sandbox where you visit the same rooms over, scan for interactable parts (some of which still have an unintentional outline around them that make the entire thing look cheap) and do that over and over again to collect some "tech parts". After you found the three spawn spots for interactable loot you're basically left to grind and continue whenever the game proceeds to the next stage.
Every now and then a monster interrupts you and you're thrown into a very very basic combat scenario where you either wait for time to run out or you click one of the like 3 options you got.
Lose and you're rewarded by some plain and boring monster on quarian action.
Progress itself seems to advance by collecting enough "tech parts" to complete certain "quests" or simply by sleeping often enough.
Later on some decryption and monster dog minigame is introduced which feels entirely tacked on. You click when the slow moving cursor is in the right spot. That's it.
To the game's credit all of its mechanics are explained, though I found myself stuck a couple of times on how to advance the game progress.
Visuals:
You can judge the visuals for yourself. To be frank I find Tali's model rather ugly. The remaining models are at best mediocre as well.
The stop motion animations were not particularly impressive with short loops of a handful of key frames at most.
Scenes, just the ship frankly, are not well lit but at least they are somewhat consistent.
Plot:
Tali is on her pilgrimage, tries to scavenge some derelict ship and immediately loses her ship, gets raped by some wild monster and now "works with" some pirates trying to fix their pirate ship. That's about it and about as far as I read before I just skimmed through most dialog. I'm familiar with the setting though you really don't need the background knowledge to get what's going on. You might recognize the species and are immediately familiar when organisations like the Alliance or Cerberus are mentioned. But for all intents and purposes a lot of the world building is thrown out for the lewds anyhow (a futa Asari, Tali being far too unbothered by her suit being damaged, Tali being a nympho...).
Given those liberties I didn't expect much from the story and I certainly wasn't looking forward to 5 to 10 minutes more grind before the plot actually progressed.
Conclusion
Granted, I'm not a big Tali or Mass Effect fan and I dislike monster rape games. But even despite that, I fail to see how this game is held in the same regard as more well narrated, less sandbox-y and/or visually pleasing games on this site.
If you're not head over heels into Tali and/or monster action I wouldn't bother with this one.
