The Las Dunas Soccer Stadium is unfair because of its shape. On the blue side, the fence makes a strange turn and cuts off a corner of the soccer field. There is no such thing for the red team. This gives the blue team less area to play with. This is obviously unfair, especially for an official map.
There is no logial reason why this is the case. IMHO the playing field should be perfectly symmetrical so it is fair. The odd, rough shape is not the problem, but the asymmetry is. I also think it's OK if the graphics are not perfectly symmetrical, especially for all the eye-candy that lies outside of the playable field. I'm only talking about stuff that affects gameplay.
Please make this arena fair for future releases. Thank you for reading.
