At this point it doesn't really matter how many games and things of such you want to play. Just convince yourself that this girl isn't worth it and try to enjoy yourself at the concert with her. If the concert is awkward and feels sour just try to meet some other girls there. Really hot chicks are completely meetable at concerts. A girl that isn't your GF isn't worth worrying or contemplating about. In close, just wait til the concert and see how she reacts through that venue, forget all this myspace and 21st century game killing.
