For the second game, I would definitely try out the “content restored” mod that reintroduces a lot of content that was cut from the game due to rushed production. Otherwise you can just play the versions on steam or console.
The Steam one had an update that includes restored content by default, but there are fan mods that go a little further. I will say though that a lot of people overestimate how much was cut and think the story is confusing because of cut content, and not because they didn’t go through the effort of figuring it out through dialogue or looking around.
