OK, I recently got the Doom 3 so I dont need the Doom 3 demo anymore, so how do I uninstall the demo?

Any help is appreciated!

Go to the folder you've installed it and see if they have a uninstall executable. If they don't, simply delete the folder and make sure the link at /usr/bin of Doom 3 is also gone. It's usually save to do this in Linux, it's not that some registries will be kept or anything

I've been getting purple in the face trying to find any information about uninstalling the doom 3 .run package (Id's official one). There's gobs of stuff about the .rpm format (in my O'Reilly Linux book and on-line), so I get nervous that there's something "deep" about uninstalling a .run package. Is it really that simple?
Doom 3 for Linux (mine is SuSE 9.2) has a lot of graphics bugs. Invisible (unrendered) furniture, spider monsters with their legs on wrong, levels that don't load unless I change the path to the graphics inside the .pk4 to lowercase. The support has to (I'm talking to id, here) elevate much.
