Nice guy game isn't really game from what I've seen. To me it seems to be good looking guys walking up to women, over-complementing them and essentially begging for their number. I've only seen a couple of examples though.

If you want same day lays, I think your best bet is going direct. Soul (Love Systems) is usually able to fcuk a girl within an hour or two by just being direct, confident and honest with her. Mystery's courtship process takes 7 hours. Go figure.
