18ZOO

18ZOO is an 18xx game set in a fictional ZOO, designed for 2-4(5) players and playable in about 100 minutes (long time players can find here poisoned trains, short amount of tiles, tokening, lot of incentives in buying train and rust them)

There are many features that makes it highly distinguishable:

 No need to compute any division or percentage during the game - revenues are pre-calculated
 POWERS/INVENTIONS (privates) bend some rule in a FUN and exciting way - 16 of them appear throughout the game
 Companies are opened in a sort of ring order - first choice (and second choice) will make the game afresh
 train RUN have a growing threshold in order to increase the stock value
 eurogame style: the goal of route building is to be efficient throughout the game, instead of trying to achieve a local best run
 Villages/dits and Hills/Mountains are not upgradable (generally) so that route building is different in each game.

The goal of the design of 18ZOO is to have a game that last only 90-120 minutes, with the full narrative of a 18xx (both Stock Shenanigans and Operative Shenanigans), approachable by a wider audience (low calculus involved).
