Wildlands is still a great game. It is set in 2019 Bolivia, you work to take down cartels one region at a time. It’s fun both singleplayer and co-op for up to 4 players.
Breakpoint is set on some semi-futuristic Elon Musk type fantasy technology island with drones driving and flying around. The map itself is large and varied, it seems like a South Pacific type environment. Breakpoint initially did a lot of things worse than Wildlands, such as not having AI squadmates and needing to level up your weapons. But since then the game has been updated with a lot of options to fix almost everything, and even add a lot more content. It’s a lot to get used to but ultimately still a lot of fun.
But first play Wildlands, it is fun right away, and more realistic overall.
