Hello,
I Installed game X3: Reunion from GOG, game wont start, terminal spits out the following
karuros@karuros-desktop:~/GOG Games/X3 Reunion# ./start.sh
Running X3: Reunion
Language detected: English
./X3R_config: lib/libz.so.1: version `ZLIB_1.2.9' not found (required by /usr/lib/i386-linux-gnu/libpng16.so.16)
I already looked in my /usr/lib folder and I dont have a libz.so1 library, the closest I have is in the /i386-linux-gnu folder and it is called libzstd.so.1
the installation folder of the game does have a lib called libz.so.1 but I am not sure how it is failing
I tried copying the libzstd.so.1 to the game's lib folder and renaming to libz.so.1 to replace the original libz.so.1 file but it did not work, terminal spits out more errors

Also can you share

This way we might be able to figure out what library you are missing and install its package, maybe.
Also, can you find the binary executable file of your game in the ~/GOG Games/X3 Reunion folder, and share the output of the following command:
ldd your-executable-file
where you replace your-executable-file with the name of the file. (If you don't know which file it is, opening start.sh in a text editor and reading it might give some clues.)
Here is an example of this command from my PC (for a different game's executable of course):
karuros@karuros-desktop:~$ apt list --installed | grep libz

this leads me to believe that the binary executable file that you are asking about is the X3R_config file located in "/home/karuros/GOG Games/X3 Reunion/game"
ldd X3R_config
/lib/i386-linux-gnu/libz.so.1
/lib/i386-linux-gnu/libz.so.1.2.11
/lib/x86_64-linux-gnu/libz.so.1
/lib/x86_64-linux-gnu/libz.so.1.2.11
It looks like you need the files to be in /usr/lib/... but for some reason you have them in /lib/...
Let's create links to them in /usr/lib/... and see if that works.

I did confirm that your code created the link files in the correct location but it did not help.
local lib_path32="$CURRENT_DIR/lib/:$CURRENT_DIR/game/lib/:/lib/"
Other than that, you might try copying the libz.so.1 file to the lib folder inside the game's directory. That's where it seems to be searching for it.

What's the version of zlib1g:i386? This is what I have on Mint 20

Also, the there already is a libz.so.1 file in the lib folder in the game's directory
