Already tried win version on Wine and PlayOnLinux.

PlayOnLinux won't install the wine version 7.5 when I highlight it and click on the arrow pointing right. So stuck at that point doing it that way.

Wine loads it but brings up the wine desktop blue screen then just shuts down.
I do have 64bit wine and have tried to load the 32 bit but not doing something right cause every time I bring it up it tosses me the your using 64bit wine.
I was able to run Two Worlds on wine and it works but without sound.

I would rather use the straight up Linux version but it won't start the game so I tossed the .sh start file in terminator so you can see what I'm guessing is dependencies? that aren't there. I have no clue how to get it right.
This is the output from that:

Tried finding some of these in repositories & internet to install but not getting anywhere.
Maybe Arch is just incompatible?

I can get the Linux version to work fine in Ubuntu 16.04 (after installing dependencies) but Manjaro runs much faster on my machine. Maybe since it is only 3.2 Dual core. It will also run in Mint 18 but I really don't like Mint.
I would really like to use my preferred Manjaro 17.6 Linux if possible. I know Arch is different from standard Linux distros.
I have a NVidia GTX 1050 with 2g mem and 8g ram.

Any ideas to get it going would be greatly appreciated. Thanks.

I went here wiki.archlinux.org (can't add link) thinking could fix the multilib thing but I don't have the /etc/pacman.conf file they are talking about. Do have pacman.d and there is a mirror file there but no multilib in it to uncomment.

Out of curiosity I opened Terminator and ran a database sync and think the multilib is enabled????

# pacman -Syyu

there is nothing to do

I did a list command on the multi and it did give me a list but couldn't find any libgtk on the list..

I do have GTK2 and 3 installed from the software add/remove program.

I'm digging everywhere I can here but I think I'm confusing myself more than helping.

OK I (not super sure) think the dependencies part is ok now as I catfished for the pacman.conf and saw that it was under /etc just not the part I was looking in.

It is bringing up the little launcher box but now I get:
