Haven't been able to get Wineskin to work with lineage15.com's Windows client, not sure why but once it launches, it says the binary is expired. If I set the date to 2010 then I it tries to launch but it just shows a jumbled screen that looks like it was rendered by a defective GPU, and throws an error about not being able to find GameGuard. Weird.
I finally got things going using Oracle's free VirtualBox with Windows XP. It actually runs great!
