Well, it's a good point, but wouldn't it be very monotonous with only 2 promotion teams, since it is 2 relegation spots in the Tippeliga?
I remeber FIFA2003. It was a very good game because it even included norwegian 1. and 2. division teams + the Tippeliga. Sure the 1. and 2. division teams didn't have updated players, and the kits were basic to, but for example Tromsø IL has red and white stripes in their kit. And in the 2002 season they were in the 1. division, and I remeber when they promote to the Tippeliga when I played FIFA2003 for the first times how happy I got since my favorite team was there, with low detail of course, but still it meaned alot to me...
Sorry for my babbling, but think of it. FIFA 2003 was very detailed, and I would be very happy if this were in FIFA 2005 (I don't understand why they didn't have this in FIFA 2004), but I don't think so.
