'inner game only' guys (no lines/techniques etc)

I'm curious about what it is you do in set that makes you better/gives you an edge over guys who have never heard of game?

I've realised that the whole PUA/gamey stuff (negs, disqualify yourself etc) doesn't really 'work' how we're told it does hence nobody seems to promote in anymore

But then, I realise that when I'm in set and approach a girl, my interactions are the same as every other guys. I don't feel that I have any edge over my competition. We're having the same conversations with girls (who are you? where are you from? what do you do for fun? etc) that other guys do since we don't use 'outer game' (negs, disqualifier etc)

Is it basically limited to things like concentrating on eye contact and stuff like that? (maybe non game guys aren't aware of eye contact for example)
