Besides these specific tracks, at least for the cities, it would be nice to have some "free roam" areas that include not only the area where the track(s) are located, but at least a little surrounding area, hopefully extending a bit into suburbs and surrounding countryside. And would include both race fans and regular pedestrian traffic - would make for some great photos.
Course maker DLC:
A new course maker for GTS. Would include all types of environments including canyon & desert, mountain, rainforest, snow & ice, tropical coast, etc. as well as a variety of urban types: small town/village, classic European, modern high-density, etc. And all types of tracks/races: on-road, off-road, circuit, point-to-point, dedicated race track, informal street race, etc. And customizable elements: houses and other buildings, water features, level of vegetation, fan/pedestrian density, billboards with our own custom graphics, etc.
Miscellaneous DLC/fixes:
Make the driving line dynamic again.
Make the music playlist editable and allow for uploads of our own MP3s.
Let us choose what graphics are used for the home screen background and screen saver. We should be able to use our own in-game photos and videos, and it would be nice to have the option to turn off various items like the historical screens or the 3-D models of cars (also in race loading screens) that make the console heat up unnecessarily.
