You can install a windows program anywhere you want as long as you have the right permissions to do so (write access). /usr/local/games/ is normally owned by root, so you would have to do it as root (sudo). Why you would want to do this is another thing. You will still get the messy windows structure in this directory: Code: /usr/local/games/The\ Game\ I\ Installed/drive_c/Program\ Files/... You could also just install it the ususal way (into .wine) and just symlink the directory, but there really isn't anything to gain. Windows apps are meant to be installed in a windows way. You can't separate them from the registry, like you can with unix apps.
