If only your distro would support more than one desktop.

I will say though, Gnome dropping support for other window managers does suck. That is them removing infrastructure that non-(or semi) Gnome users depend on.

Wolfenstein 3D is a lot less impressive than Doom. Doom was faster and more complex than other games, where as Wolfenstein had a strong and appealing gimmick but was slower and less complex as a trade-off. In-line with the expectations around compiled languages.
