A Few years ago I strolled into Target and saw on the bargain shelf (9.99 and under) Ultimate Trainz Collection. I bought it and took it home and installed it on my Dads computer (his laptop at the time was the only windows computer in the house). I enjoyed the experience. And I was impressed with the sim (though there weren't any steam engines and I didn't know about add ons or the download station). About a year ago while looking at the same shelf at target I saw a pack for TS 2009 and TS 2010, and I knew I had to have it. But also I had been want Train Simulator 2014 from Railworks. I did get that for Christmas, but was disappointed in the method of installation for the game. Once it was installed, it wasn't long before it was uninstalled as it was operating very poorly. ANy way to get to the point. I like Trainz for several reasons. 1, the installation is easy and the instructions are simple to understand. 2, there is a large amount of freeware for trainz, and since newer versions of trainz accept older files it is easier to find what you want. 3, the way the menu is set up is easy to follow. 4. The surveyor application makes route building and consisting much easier (especially since we now don't have to use trackmarks to place consists). 5. The display settings are separate from the game itself which makes it easier to tweak things, which is the reason I had to uninstall railworks 4 because of an error that occurred after I tweaked the settings. So my question to all concerned is why do you like trainz?
