.kkrieger
Most popular first-person shooters filled one or more CDs or DVDs at the time, but the game uses 97,280 bytes, over 7,000 times less than a CD (700MB), or 55,000 times less than an Unreal Tournament 2004 installation (5.5GB). That game normally comes on a DVD. .kkrieger's developers say storing it normally would use about 200–300 MB.
