This and only this, video games aren't movies fucking kill yourself.

Silent protagonists are an absolute cancer and those that like them are socially inept and probably permavirgins. Obviously titles without any real conversations like Kirby or whatever are fine but these dialogs are beyond gnarly and anyone who can just shit through this without cringing is a socially inept permavirgin.

>But but YOU are Gordon, just imagine your own lines

Doesn't matter because no one is responding to your lines so the dialog is still extremely unnatural. Either the main character does not ever respond and people somehow continue to talk to him finding that normal, or in reverse no one responds to the main character. But I gather that that's how the "conversations" these permavirgins that enjoy this have anyway.

You'll just end up with incredibly unnatural lines and an extremely uninteresting and bland protagonist to allow lonely losers with no social skills some escapist self-insert fantasy.
