Furnace Duel Is one of the greatest auction games ever actually BETTER as a 2p only game? (yes!)

About Furnace Duel, from BoardGameGeek:

Furnace Duel is a 2-player follow-up to the popular Furnace board game. It is playable both in standalone and campaign modes, in which you compete for global industrial domination in a series of games played on six different boards. The core gameplay in Furnace Duel is the same as in the base Furnace game. You bid for Company cards, get them or receive compensation, then use your cards and manage resources in order to gain the most money by the end of the 4th round. However, here's no compensation effect on top of the Company cards. You receive compensation by claiming routes on the game board. The value of your disc shows how many times you may use the effects of connected Cities (in any order or combination). At the beginning of the game, the only available tracks are the ones leading from the City corresponding to the card in question, but as your network grows, you gain access to new tracks and more lucrative Cities. Each of the 6 game boards has special rules and features. In the Campaign mode, you accumulate Campaign points awarded for winning a game and for fulfilling Achievements, both general and board-specific. The runner-up gets a board-specific bonus that gives them a bit of the upper hand in the following games. Cards can be upgraded with the city effects. There are Shipping companies, which are one-shot cards with a neutral brown disc printed on them – it is considered a bid of a neutral player. -description from the publisher
