i think corners are harder, i find they go a lot further with less power so a lot of mine go past everyone and out for a goal kick or throw the otherside of the pitch!!!
penalty thing doesn't happen to me, although when i foul right on the edge of the box, the commentator says "oh, IS THAT A PENALTY!!!!!!!!!" at the top of his voice, i have a heart attack cos it was clearly outside the box but close enough for a little doubt. and its just a free kick. adds to the tension of a good game though. (it always seem to happen in last 5 mins)
