As a new Xbox One version player, I have only about 13 hours under my belt. There are a few things that jump right off the bat that would be nice if implemented:
Detail more clearly the different characteristics of each vehicle from in-game, so I don't need to go hunting through forums and websites to know the difference between each truck.
Add something else to on each map. I have carried logs, cleared watchpoints, and found locked vehicles. Add more tasks to do, like finding secret spots, secret items, etc.
- Add some sort of NPC interactions, like traffic, quests, etc.
The best part of the game for me is the back roads exploration, so if I could complete a few tasks in the meantime, it would be even better.
