Id say this is arguably one of the better sand box games with a tremendous amount of content
but there is a lack of proper sex renders which might be a turn off for most. I would say to give this game a proper shot tho.

One of this game's drawbacks is the poor models, partly necessary because of the mechanics of the game requiring lots of versatility. The GenAI mod, available on the game's Discord, attempts to fix this. I've had good results with it so far, on just mediocre hardware. The mod's thread contain install instructions, first to get a stable diffusion webui service up and running, and then the mod installed to call it and generate on-demand images. With better hardware you can run more complex generation routines, but I'm keeping it simple to maintain sub-10 second gen times. It's still early in the mod's life but it's been stable with only 1 bug so far.

Anyway, figured I'd mention it, seems a good addition if it's feasible for you.

Is the mod a large file or a small one? If small you could just attach it to your post for those of us who don't jump on random Discords. Or point us to a download link. Thanks!

 

[Shooter682]

There are a good active mod crew working on this game. Check discord under the mods and there is a development version that is being updated as they go and a beta version trying out new game play

Wasn't really sure what the reposting policy was of mods around here. Assumed it was pretty lax but figured play it safe since it's not my content.

I also generally don't join any kind of porn-focused discord servers, even this one, but did this once so got current D/L. Can't promise any updates!

the readme files and stable-diffusion-guide.html included in there should help you get it going.

A downside is the characters from the orginal game don't look similar unwise a great game.

 

[skybreaker1780]

Nice to see a continuation, but sad they still didn't make any new renders

 

[Shooter682]

Vern was working on a DAZ update for the characters except it proved to be too large of a task and He dropped the porject. I will share links for the major mods

[ramvivat]

[Shooter682]

How am I supposed to get them off birth control?

 

[justted]

How am I supposed to get them off birth control?

get them to 160-180 ob then ask them to stop taking it.

Just had my laptop crash while playing this game, I think it happened because it was having to generate too many characters and I was overloading my hardware or something.

I was searching for someone through all the locations (didn't know her name, so I was looking through all of the ??? characters in a bunch of locations) and after like the thirtieth or fortieth in quick succession, the displayed character model was a black rectangle and then my laptop black screened, and I had to reboot it.


Edit three months later:

I've been playing it some more, I downloaded a recent version, had none of these crashes since. I don't know if it was a problem with that version or I caused it by attempting to download that AI model changer or whatever it is, but on a fresh install there's been no crashing problem.

Wow started this a few weeks ago and quickly became one of my new favorites. Now that I am in late game, I have noticed a few times when it shows an event in the bottom left but I can't find it on the map. Anyone know why that could be? Regardless, really enjoying this one, and recommend it highly.

 

[justted]

Any word on this project being worked on, the best mod ever made for this game!

 

[master101]

Ive been playing this game for the past 2 years. Really glad an active dev picked this game up after it was abandoned to continue to work on it. They have a github for the game thats constantly updated, but only package a game for sites like this every 3-6 months (or longer sometimes)

 

[coykili]

Lots of time can be sunk into this one, honestly it seems like the sort of game ai generated images was made for, i hope it branches out in that direction at some point
