That is the unfortunate problem with these issues. we are not playing a make your own decision game written by a AAA dev studio with a multi-million budget with numerous completely different storylines.
All points must converge at some point. We are following a very set story so regardless of choice (on chosen LI path), they must still all end up at the same place or as a previous poster said, he is then not writing one story, he is writing 25 seperate stories. That just isn't feasible. So as we know for sure (on Sages path) Mel is going to call to Chad, the easiest way around this in all other paths is for the call to have still happened, but she lied instead. Chad is told about the MC and Sage, Chad is pissed, Chad is out for you. You have to understand the 'illusion' of choice here. Regardless of what you do and who with, you still end up at the same place. The trick for DPC is to make the differences inbetween interesting enough to want to see them. You'll still end up at the same place though. Because ultimately, whether you like it or not, you are largely on rails.
Does it cheapen anything? I guess that comes down to personal opinion, but that is unfortunately what has to happen in this type of branching game where the divergences end up at the same place. Just something you have to accept. Or, we all have to wait exponentially longer amd longer between updates for him to deal with 25 completely different branching storylines where eventually, it will be an udate per LI as he has given himself so much work. Unlikely to happen.
Look at like this. if you avoid everyone...you still act like a lovesick cucked husband and walk out of Maya's dorm. You still go on a date with Jill regardless of what you did. You are on rails and you are following a predetermined story. (That doesn't mean we can't have 412 different endings, but there will be more points where regardless of choice, regardless of LI, you'll end up in the same spot as everyone else). For that to happen, there has to be times where you'll just have to roll with it.
