Once the TCU onlining was decided, the fight just became about carnage: who could kill the most the fastest. The fleets committed by both sides represent a staggering amount of time, effort, and ISK. Each titan costs about 100 billion ISK (up to 160 or even 220b for particularly expensive fits), which can be purchased for about $3,000 USD by buying game time and selling it to other players for ISK. More than that, though, to build a titan requires several weeks and a nice quiet undisturbed area of space, something harder to find in the current climate. Supercarriers are similarly challenging. Dreadnaughts and carriers, while not as difficult to build, still represent a significant investment of effort on the part of an industrialist somewhere.
