Not sure if anyone else used to play this but found that some guys are 'rebuilding' the original on open source. free download here (http://www.openttd.org), hours of fun :)
I saw this years and years ago, and it was pretty interesting then, if a bit clunky compared to more modern games, I had no idea they were still actively developing it. That's the beauty of open source, a classic game like this lives again. Wasted many an hour on the original and earlier versions of this.
