I spent almost a whole day trying to make Jade Empire work on Linux, but no dice. I have the GOG version (which ran fine on Windows), but when using Wine it just shows artwork and then freezes. I've seen several people with that problem even on Windows and literally no one fixed it (well, one person supposedly did, but they just used Win 98 compatibility, and that didn't help in my case either). Exhausted and out of ideas, but would really want to make it work.
On another note, Linux terminals are really cool with how customizable they are.
