Considering the remarks about the useless grind, I'll wait until this is finished or modded to bypass it.
Even with the cheats to avoid most of the grind, i would advice u to wait a bit for more scene rewards... dont get me wrong, the scenes that are in there are well done but are mostly vanilla, nothing really juicy in the sex aspect (except ur boss and his wife doing it, if u like to be a peeping tom), so it feels like not much.
The grind in this is insane for no reward, watching porn never works and usually fucks up the game so no real way to increase lust but even if you do you face even bigger penalties from the women. I really wanna like this game but I am not a masochist...
I got lust up really easy by save scumming peeping on the girls, even before i tried with the easy cheats that are in the OP and also watching porn works, i dont know what u mean, once u get hacking level 10 u can watch once a day, thats all, increasing not only lust +1, but mood aswell, and this last aspect is even better than watching any tv for all that matters... anyhow, not much in rewards, i give u that.
As others have mentioned, this game is extremely grindy. But I can live with that as long as it's a true sandbox game.
Thats the way i felt this game, it really felt like a solid sandbox and im glad i tried it, even if i didnt fap once or saw very little sex in there... i think it deserves some time before any real judgment, its just the v3 after all... i see it like a solid base to develop the sex scenes later. Cheers!
