If you want good graphics and still the possibility to have object driven games, get Xonotic. It has an objective mode (I don't know how popular it is but it's there).
Xonotic is broken on my system and developers know about this bug.
Basically, if you have XFCE, the key combinations that xorg sends _on non-english keyboards_ are a bit different.
Instead WASD, inside Xonotic keyboard bindings menu, I get "World_35", "World_36" and so on.
Urban terror works fine there. And in xonotic, I cannot move. This is specific only to key selection menu, the name menu works like charm.
It does not help to remove all languages, except english - it depends only on non-english keyboard.
