About the cheats, I'm one of the few playing with only the energy cheat ( cheatcode : energy or energyrelated ). It's not popular because the code isn't in the main post, so not many people know about it. But I find it really fun because you have a lot more freedom with infinite energy but still have the interesting gameplay of managing stats and lights. Money is annoying though since it's completely locked behind the green light.
About incest I thought someone could just select at the begining if there is incest or not and then follow any walkthrough.
no the cheats are the posted the same way
so when you get to i know her you can chose these
cheat - gives you max energy, spells, stats, etc.
related - make the player related to the Maywoods aka turns on incest
cheatrelated - gives both max stats and incest cheat
energy - give max energy but nothing else
energyrelated - give energy and turns on incest
phone - give phone info on day one but nothing else
phonerelated - give phoneinfo and turns on incest
and yes they are in main post think they are in Dev notes click down under cheats click down
