What a little gem! This one has been sitting in my unplayed library for months, until a few days ago. Like many, I got it off of one of those cheap sim bundles. There are so many crap simulators flooding the market these days and I figured this one would easily fall into that category. I was wrong. It's actually quite good and alot of fun to play. A short 3 bridge tutorial gets you started on the basics. After that you're on your own.
The object is simple. Build various length bridges to support cars, trucks, trains and drawbridges that can allow boats to pass underneath, all within limited budget and material constraints. There are several different bridge types and material types with different costs and construction methods. The game claims advanced physics simulation. I wouldn't know because I'm not a mechanical or civil engineer so alot of trial and error are needed on my part.
When you're ready, you press the simulate button and watch how your bridge performs as people drive over it. If you did you're job right, you can move to the next level. Make a mistake and watch the disaster unfold in rather comical fashion. Stress analysis tools and a simulation speed slider help to pinpoint where the failures are occuring so you can beef up construction or use more expensive materials to try and stay together.
A neat cinematic camera view and even driver camera makes things interesting, especially if you want to see what it's like tumbling into a ravine because your bridge is poorly built.
Definitely recommend for sim fans and engineers.
