If the wee 10 Gnomes isn’t quite up to the speed of your gaming experience, I recently found out there is a gnome mode in Half-Life 2: Episode 2, where you can carry a wee gnome and deliver him to a rocket.
I’ve never played Half Life 2 myself, but any game with a gnome mode gets my vote. I’ll have to put it on my wish list this Christmas, along with a gnome-sized console.
The wee folks over at Concerned created these great gnome scenes.
