I really enjoyed that game but I made the mistake of trying to finish my highway before beating what I think was the final boss so I burned out and never finished it.
The default cooperative online mode ends up being a lot less interesting than going at it entirely by yourself offline from start to finish. All the clutter wrecks the immersion/isolation while the freebies end up wrecking the leveling.
