Self-explanatory title really but considering how the popular places in London and the like are packed with people that can get in the way of your game big time. Picture the scene - you see that target you just have to approach and as you try to move quickly, well you can't because some dope is in your way or could bump in to you or they just felt like being a total idiot and randomly stopped in the middle of a crowd just to pick his nose and flick the boogers everywhere, and bam - that hot girl you tried to approach is totally out of sight! Or it seems almost physically impossible to get sideways round a crowd or U-turn to get to her before she has become physically unobtainable - all because of a great big cluster of people in yer way.
I remember a very witty article when Andy spoke about the 7 villains of daygame http://www.daygame.com/2009/articles/the-7-villains-of-daygame/
but I think there is an extra daygame obstacle that can be quite a challenge to overcome.
And thinking about it, with the Christmas season coming very soon the streets are bound to be even more packed than usual and it seems inevitable this particular daygame villain could become an even bigger monster!
