gp4Ah right I was under the impression you couldn't get it running with win 10. What are the essential mods I would install?
official patch
no cd exe
gpxpatch
zaz tools
If you have all those installed properly you can go on to mods. See this sheet for what's available and were https://docs.google.com/spreadsheets/d/1BpvZhRt-FPHP2U4LyY714WN_s1TyoaCqzLZOJl2-o6Y/edit?pli=1#gid=0
