The biggest game in the world, I think

《Myst IV: Revelation》, a new continus of the most famous classic adventure game Myst, could be the biggest game I have ever saw before, which release at double DVD9 capacity and need 12GB hard disk spaces to apply installation (to avoid frequent DVD-Drive reading). Aooooooooo........., I hate this way, I can never have 12Gb free space in my HD, which even bigger than any one of my HD partitions. So what should I do? To rush to e-marketplace and catch a new 160Gb HD in hand or To put this game in my cabinet and wait for a while, that's a really big question. ^_^
