THe only thing that bothers me about the game, are the pregnancy requirements that are needed to advance certain quests. I'm not sure if trying to use a save editor to pad those stats would be worth the risk, the obvious risk is if the game ends up glitched or bugging another quest , and or the MC's other relationships.
I've played the game cleanly, putting in the grind to build up stats, learn skills, and so on (I've done a fresh start at least half a dozen times). It's the downtime of in-game play to skip days far enough along to meet the requirements.
ANd is the requirement of not going (I think) 5 days without visiting the various ladies, still see a loss of affection points? I haven't really gone more then 3 days, after 3 days I visit and interact with all the ladies.
