I really enjoy this game. The Parkour is easier, though at first it will be difficult since it is the start of the game. It gets easier.
I found that to get a full rich experience stop and actually be a part of the community. Example: a lot of lore and back story about what has been happening and what the GRE and the rest of the world did can be best learned by sitting at the campfires and listening to the people talk. Also listening to the people before you talk to them for a mission gives richer experience as they frequently are giving a back story for the mission. The game isn't all about the player getting what they all of the time, being patientand listening to people pays off. I have to wait, and listen a lot. Which is different and I like it.
The combat, if you play on easy it will be fun and easy, lots of one hit kills most the time. If you play on hard it is hard.
My favorite is the plus version of the game you get after you win 1x.
There is a more difficult setting the combat really changes and requires a lot of strategy and the bad guys tend to be harder to kill and a lot of different tactics, including stealth, upgrading you "gadgets and parkour attacks, are needed to be successful.
It is beautiful and a treat to play.
