It can easily be skipped. It's not like the main path disappears. You'll be able to fuck tiffany anyway and Becca too. That's not going to change. It just opens up the game to a route that includes all the fans who pay for that route to be set up.
No shit... but Tiffany when (been 2 years bozo) and we've already smash Becca... in the non-redux non $20 version. The main point being, enough time spent on the NTR.
