Great, I am just about to do an upgrade, I will probably pick it up after that. Wedge22, is there any kind of levelling or perk system?
There is a levelling system but it's kind of a joke; you gain points by completing challenges (from normal gameplay) that you can 'spend' on skills. By the end of the game I had almost every skill maxed out and I didn't even complete all the available challenges or have all map zones cleared of enemy threat. Similar to Dying Light it is possible to have every single skill maxed out before you beat the game.
On the flip side there isn't an overwhelming number of things to do so it's not like the map is this huge daunting task to complete, which was nice.
You need to collect 'scrap' to buy upgrades for you and your gear. This is the biggest grind of all, and they leave it up to you for how you want to do it. Exploring the map and clearing enemies has the biggest return but gets tedious if you're an impatient gamer. There's a fast travel exploit that lets you zip around the map really fast even when enemies are surrounding you, but you miss some of the endearing dialog from your car passenger, who really made the game fun for me.
I had 2 mission glitches where the waypoint didn't update and show me where to go, one is a well known bug that may have been patched. I was able to muddle my way through with help from the forum, and complete the other race by retrying until I found the correct route and winning it.
It does look like the best wasteland I've ever seen in a game, and that should be appreciated, full price is debatable though, unless you're hardcore madmax fans.
