Railroad Tycoon II: Conquer 3 Continents (Special Edition)

This is one of the many repackagings of the original Railroad Tycoon 2 game. This one comes with 3 scenarios from the full RT2 game ("The Iron Seed", "Excess on the Orient Express", and "Cape to Cairo").

Thankfully, all other elements are present from the full game, including the stock market, opponents, sandbox mode (which makes up a lot for only having 3 scenarios), and building.
