I hate the self-insert. I think the lack of voiced MCs is also due to this. Don't make me talk about old games, like the mobile ones. It wasn't uncommon for the MC to have no lines. She would just nod, make gestures, or you'd follow the flow of the conversation based on the guys' reactions and responses.
Well, I get that the target audience is japanese, but it feels weird to think that 2D characters are speaking directly to you. That's just my personal opinion, not a big fan of yumejoshi content.
For this very reason, I was put off when I saw Sympathy Kiss. Beautiful art but the eyeless MC is a big no-no.
