Locomotion, Chris Sawyer's

If you ever played OpenTTD don't play Locomotion after it. You will be frustrated with controls, UI, economy just like I did. There's no way to group your vehicles, no way to clone vehicle with orders, no way to build rails and roads with your mouse (awful thing, took me 1 hour to connect 4 train stations with single rail and couple of junctions in the middle, not to mention signs - I would achieve the same in OpenTTD in 5 minutes). Once I connected it I realized I've lost alot of money because it won't pause (loss and restart). Next time I tried to connect same with truck routes, after 30 minutes it was done... just to learn that 1 truck hauls 5t of Ore and I'm in loss again. Definitely not recommended if you're used to play big OpenTTD maps with 1000 trains, you won't live THAT long to build all of your tracks :)

Open TTD, short for Transportation Tycoon Deluxe, is both free, and a HUGELY better game. Also, do even a bit of research, and you can find a mod that adds dozens of different industries, and industry chains. There is absolutely no reason to purchase this game, even at the low price.

This is the spiritual successor to Transport Tycoon Deluxe (TTD). TTD was a great game for it's time, but had a poor interface like most games of it's time. 10 years on, this is what the dev came up with. Nothing has changed, except that it runs on more modern OSes. The interface still sucks. If you want to set up any road transport, be prepared to click on the same set of stops for every truck/bus you buy. And you will need heaps, because they have barely any capacity. As most other reviewers have pointed out, OpenTTD is a open source clone of the original TTD, and it is a far better sequel. There is a great game in here, it's just buried under a maddening clickfest.

For some reason it crashed on launching the game. After crash super lag for my pc oddly enough.
