About Turbofans, from BoardGameGeek:
Turbofans is a action- and set-selection game of operations at 15 major, U.S. Airports and 20 minor airports, over the course of 50 years, from 1960 (about the time turbofan-powered, jet aircraft first came on the scene in the U.S.) to 2010, in 10 5-year turns.
The Players will alternate taking actions, performing one or more such actions (depending on how efficient their company is) to purchase Aircraft or Hangars, creating new Flights, or upgrading their airline, so that it is more effective in future actions.
The aircraft return net profits every turn, but each model of aircraft is different and can generate different profits, for varying numbers of turns. And aircraft will be forced to "retire", as newer, better aircraft become available.
Victory conditions are two-fold, and are scored at the end of each turn - most cash on hand, and most major airports under control.
In addition to this, the game has a Bot system that not only allows every game to have 5 companies, but actually speed up play in the process.
Turbofans comes in two flavors - the Introductory game can be played in 60-90 minutes, and the Standard game comes in around the time it takes to play most 18XX games. There are also optional rules, regional startup scenarios, and more.
