Trade Wars, and a branch you can see both sides of
TRADE WARS 2002 is real now. Ten sectors, seven ports, twenty-four turns. The port classes are the actual ones — three letters for fuel ore, organics and equipment, B where the port buys from you and S where it sells to you — and the whole economy is finding two adjacent ports that disagree with each other about what something is worth. The Ferrengi are in sector nine and they want your cargo, and you can fight, run or pay. SPECTRE is a real split screen. Two viewports scissored into the same render target, two cameras, one post pass over both, and a hard seam down the middle. The speculative timeline lives on render layer 1, which only the second camera can see — so the right-hand pane genuinely contains things the left-hand pane never will, which is the entire point of the section. Steering is mirrored. The token you carry out of the branch that gets discarded is only reachable in the pane that stops existing. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
