Impressions of the Quake 4 demo: starts with a really low resolution, requires a restart of the game to change the resolution, and forces you to watch a nag-screen every time you quit, therefore you're going to face a nag screen before you've even started playing.

When you are loading a saved game, you can't see the date/time that the save was created unless you click on it (although they appear to be ranked newest-first).
