Well, let me just say that I have enjoyed the crap out of this update.
I didn't run into any bugs! Y'know, other than the 'width error' bug during the sex scenes which are easily overcome with the up arrow method or a bit of save scumming. Those 'width errors' usually disappear though once BoN posts the final version of the update and Pepe usually uncompresses it so it runs smoother.
I liked how this update gave two hot milfs and a sister. I liked their designs. I avoided every and all gay scenes though and punched out Jason's bastard dad. I really do wonder when karma will come to effect in this game.
The only really major bug I've found is sometimes when I visit Jason's Mom Dory after getting the option to choose what position to do, the screens sometimes goes black and doesn't show anything. Sometimes it happens, sometimes it doesn't. Doesn't matter though since I just made save states for her scenes when building up her affection so I can see whatever one I want at any time. She was my favorite new character in this one.
My only complaint was the grind. Thank god the variable for popularity was in the list on Ballzak's walkthrough and that saved me tons of time with Charles' sister. Jason and Phil's moms took quite a bit though... hope their variables are found so I can skip out on the grind if I ever decide to start from scratch again.
So yeah, good update. Dunno if there was anything new outside the questlines introduced in this update but we'll see. I'm looking forward to whatever Xtra BoN adds in the finalized 1.2 Update patch since something small is usually added for the final versions before the wait begins for 1.3.
