I dislike the way the company that does Train Simulator (2014 as of this writing) does business and hoped to find an alternative to satisfy my love of simulations and trains. I have been told several times that Trainz is the superior product anyway and that I should get it. I have no idea what the people who said this to me were even thinking.
The instructions are awful, essentially non-existent, so you need to try to figure out the interface yourself. This is possible but takes time to navigate the proprietary lingo and general disorganization. I somehow deleted (or it just disappeared) a section of the HUD that gave me info on upcoming speed limits, the grade of the track, etc., and I never got it back, making the game unplayable unless all you really want to do is try to derail everything. The only online communities I could find for help were all geared toward content creation, which seems to be the only thing people really enjoy about this since, I suppose, they can charge unwitting suckers like myself for it. The section of the official wiki dealing with driving the train doesn't even exist. The "manual" tells you the keys for doing things, but this is very basic and covers none of the actual problems you'll face.
The map? You navigate it by right-clicking on individual points that are all buried in a massive amount of labeling, none of which tells you any information you might actually need until you've zoomed in so close you've lost all context. You can't rotate it, but it will rotate on its on depending on the orietnation of your train. There's no helpful color coding for cities vs. depots vs. any of the countless other things you need to find. I am offended that this map even exists.
Also, on modern computers (i7) with good graphics cards (GTX 660) -- the performance is worse than on Windows XP and an old Geforce 8600. I mean, bad. Textures won't load sometimes. When they do, they load very slowly. The game simply stops working for seconds at a time.
The whole experience was just awful, bad enough that I actually took the time to write this review after finally giving up.
I could go into more detail, but no one would bother reading it anyway. Suffice to say, I spent hours on this game just trying to do one scenario. I got through it and immediately deleted the game. I wish I could delete it from my memory.
