In regards to the ATV battery, I've been thinking about it, and whether or not they make it rechargeable or not, I think a possible solution would be to make it so the battery doesn't affect whether or not you can start the ATV. Like say it has an alternator, but it only maintains enough charge in the battery to start the vehicle- other things like lights, turbo, radio, map upgrade, etc. would stop being able to function without it. So you'd still be able to use it if the battery went, but at reduced functionality. I suppose they could also add something along the lines of having a chance the engine doesn't start right away and you need to turn the ignition a few more times to start it, but it always starts within a set number of tries.
The controls, the only real issues I have are 1: The "press E" and "hold E" functionality should be swapped, 2: There needs to be a more intuitive way to throw held items or pick up other items while holding something, and 3: Bring back the old push/pull system. That weird "fishing line" system doesn't particularly work very well. You can't easily rotate large objects without a high chance of completely tipping them over, most of the time trying to pull a tall object upright just causes the whole thing to slide along the floor, and trying to life the bottom of an object up to lift it onto a curb or something seems next to impossible.
I actually kind of appreciated having to go through the new tutorial as they made a few changes to the game that I otherwise might not have been able to figure out on my own.
