Finally, and this is something I blame all the DVG games for: the art is amateur at best. Very bland, 3D renders of the planes and targets seem to come from the early 90's, and the art direction is inconsistent and uninspired. I wish they would stick to photographs for targets and aircraft like they have for events, or revamp everything with a beautiful stylistic iconography. Regardless, dated 3D is not the way to go. These games have such great design that they deserve professional quality art.
For me it is quite opposite. I don't like photographs in games. I prefer even this simple graphics although as you wrote they are low quality art.
