What is the benefit for either one of the paths, other than just chance at banging the twins?
I gave the twins the correct names for the first two companies and the third one I lied. They still made millions, I still got all the rewards, and Bob had a down turn in profits. I just went back and gave them the 3rd correct name and there was no difference between the outcomes for that and giving the twins 2 correct and lying about the 3rd. Other than being with the twins... and the content is "meh" at this point... shrugs. Maybe more to come... I didn't keep an earlier save, so I can't check what happens if you lie to them on all the names.
Personally, I would prefer if Bob was a boyfriend or a stepdad instead of the actual father in the game. At this point in the story, I have not seen any real negative aspects of the character. He works long hours to provide for the family. He loves his wife. He loves his kids, even if he doesn't give them much time. A flaw. But that's it. He isn't abusive. He isn't doing drugs. He doesn't drink excessively. Seems like a decent guy all around.
