You may want to include kurumin Games, it's a brazilian gaming distribution...
I don't know if it has support for english language...
I play a lot with GoblinX, but it's not a gaming livecd even though it includes twenty games like Cube, Battle for Wesnoth, CriticalMass, Starfighter, Chromium... a lot of games.. and it has nvidia drivers...
Actually it is not Kurumim a gaming distro, Kurumim Games is a fork of Kurumim made only for gaming... but, I dont' see in livecdlist, maybe we can include it... but it seems to support only portuguese language...
KuruminGames
From GoblinX Blog:
Os módulos serão divididos nestas categorias: 04_games - Muitos jogos... 07_games2 - Mais jogos e emuladores.
Translation: It will have more modules for games...
There are already Abuse_SDL, Neverball and Enemy Territory to download...
