Insofar as that makes any sense as a criticism, it appears to be that in Silent Hill there is just one PC. The horror is tailor-made to the background on that character/character’s background. RPGs contain a couple of participant; due to this fact, it’s inconceivable.
But, there may be nothing about that which actually renders a lot in the best way of problem. You can have one participant. You can even have it such that whereas there’s a group, issues are primarily based on the horrors of 1 character. Or, you possibly can have it tailor-made to every PC.
I’m extra inclined to say that whomever you’re speaking to only doesn’t know a lot about RPGs.
