That game was on no one's list of anything other than "terrible games that could have been great."
We both know that isn't true.
The only problem the game has is the baddies re-spawning too quickly, and out of thin air. Checkpoints should have to radio-in to the central city. After they go silent (which could be instant), the new baddies for the checkpoint should have to drive out from the central city. Not only would it keep baddies on the road, but it would also take a few minutes (proper amount of time) for the checkpoints be be re-baddied. It would also just plain be much more realistic.
It's its only flaw. Why the devs didn't see it as such, I dunno...
Perhaps they realized its utter perfection, and just couldn't stand the 100% reviews and GOTD/GOTC/GOTM (decade/century/millenium) accolades?
