wallpapers are a very personal thing I do belive..
I suggest you download a program called fotovac and use it to scan the newsgroup alt.binaries.pictrues.wallpaper and see what you find that takes to your liking..
Also there is a software called webshots.. it automatically rotates your wallpaper and can take pictures from your wallpaper collection and use them for screensavers...
Nice site for wallpapers, even if you don't care for games. Check out the Neverwinter Nights wallpapers there, because that one with the chick wearing seashells looks nice. It only lets you download 2 wallpapers a day, so you'll have to delete your cookies to download more than that.
