I enjoyed Foundation as well, so I would definitely play it.
My timeline for playing is Control (when it released) > Alan Wake Remastered (earlier this year) > Control with all DLCs (after AW). Alan Wake was always on my radar, but when I it finally came to the PS Collection for free I had no excuses left haha
Alan Wake as a whole did not age too well gameplay wise… but the story is just so good and the pacing is also nice. There is always something new going on and it also has the perfect length.
Funny story for the DLCs, they are quite hidden in the Remaster (you hab to manually select them from Main Menu > Chapter Select > Extra Episode 1 and 2)
I really enjoyed them, the gave the much needed context on what’s happened to Alan after the end of the main game.
