This is part of the problem. The system just doesn't work. massive dik but chick affinity etc. So far, with the exception of the picnic scene alone (to my knowledge), RP has not had an effect. So what's the point of it? it's like the whole system, remove it or it needs implementing properly.
Surely at some point in time, the RP system has to have some greater effect? Otherwise, really, what is it there for? Hidden yes, but if use the walkthrough, it tells you exactly where all the points are, and said, currently it has no real use. The system is slated for good reasons in my opion. Sure, the entire system can be meta-gamed to hell, I have numerous saves as such, but many people don't want that hassle of micro-managing the system to see/get results they want.
I completely agree it needs scrapping, it hasn't worked (imo) how I quite think he envisioned it to.
