Bridge Building Games Explored
Thanks to DIYGames for their review of Bridge Construction Set, the "the second game in the hit engineering simulation series" from Chronic Logic and Garage Games. There are Windows and Linux demos available for this title, which lets you "...design and build bridges, and then stress test them [with trains and other vehicles] to see how your creations hold up under pressure", and there's even an independent fansite, BridgeBuilder-Game.com, which bills itself as "the ultimate bridge builder game website", and deals with the original Bridge Builder and Pontifex games, as well as the forthcoming Bridge It!, which sports much more impressive graphics thanks to the Auran Jet 3D engine.
See: http://bridgecontest.usma.edu/ for a really nifty piece of free bridge design & testing software from West Point (the Army military academy). It's lots of fun and the best bridges each year win scholarships (to any college) with nice notebook PCs for the runner ups. -Bill
There is construo, which is free software (as in beer and speech) and runs on Linux. Is has nothing for graphics and is strictly 2D, but it is still a hell of a lot of fun. Plus, you aren't just restricted to bridges--you can build almost anything you like. It's like the Tetris of the construction game genre--it ain't pretty, but it is very addictive.
