It shouldn't take longer than a few hours TOPS to do all three things in the poll.
(1) I-Patch: Here's a link if you need help: - Thanks to
anne O'nymous
(2) NTR Skippable: Boolean Plot Flag, If Then Conditional Statements, basic rudimentary coding, extremely easy
(3) Character Name Change: This code is literally everywhere, this shouldn't take longer than 10 minutes.
There's no need for a poll for basic stuff that the community can help you with instantly. Once you finish the above three things, which should take about an hour, you can focus on the story.
