The first game came out in 2020 and is a launch title on PSV. The second one came out in 2023. The third one hadn't been released as of the time I came back.
Edit: The first game is pretty much the entire Midgard story, but they add a ton of side stuff. Everyone in Avalanche has a much bigger role than they did before and you can travel around a lot more of the city. People actually liked the first game but didn't like the second game because it suddenly became a lot more linear and it's pretty much just following a straight path to get to the Aerith death. People believe the change up was so they could get it out on time
