Finished off the main story of Wildlands today. Heres some stats for just the "base game". I completed all the Buchons and Underbosses. I mention this because it gives you an opportunity to end the story sooner without having to wipe out the entire cartel. An easy way to sum it up is its very GTA-ish in the way of controls and the open world aspect, but you cant mow down civvies
47 hours, 2300 kills

, there's 105 main story missions in the game adding in the side missions there's probably 200+ missions but I didnt do that many.
Some of the aspects of the game I really liked: The map is incredible. Its humongous and has a wide variety of terrain, jungles, forests, mountains, basically everything but big cities although there are a few bigger towns that are good for "urban" fighting. It ran like a dream for me, although it was a bit wonky when I first started on my 970. Once I started playing it on the 1080 it was 60+ the entire time. I was able to complete the main story completely solo, albeit I was stuck with 3 AI mooks the entire time. They helped fairly well and if they got dropped, it didnt end the mission.
Eh: Way too many samey side missions. These are mostly rebel ops and supply missions. They're monotonous and theres tons of them. I only did them when I wanted to get enough crap to upgrade particular crap. Sometimes they can be fun.
Didn't like: The AI really annoyed me at times but it was more NPC AI than the main squad. There was one mission where I had to go rescue a guy from jail and I broke the lock to the cell after perfectly stealthing my way to him and the

er just runs like a chicken with his head cut off right into the big batch of enemies on the other side of the base. I had to re-run it cause he got killed and I shot the lock this time and he didnt run off like a maniac. There were other times where people would jump in front of my vehicle for no reason and sometimes an enemy would shoot at a wall. The enemies say the same crap everytime too.
Overall, I thought the main story was pretty much generic, but I still was interested in getting to the end and finding out what happens.
I'm going to try the Fallen Ghosts DLC next as thats supposed to be really good and is a whole other campaign, but the base game definitely is worth it if you like open world games.
