Train Simulator 2016
So if you have a very powerful gaming rig, and you're craving a train simulator, would I recommend Train Simulator 2016? No. No, I do not. It's too light on content for a $45 game, and I don't support the developer's ludicrous paid DLC scheme. Which is a real shame, because the physics are great and, if you can run it in high or ultra high graphics, it can look quite beautiful. But with a promised Unreal Engine 4 version supposedly in development, you would honestly probably be better off just waiting for that instead of spending money now on Train Simulator 2016.
Train Simulator 2014
This “game,” if it can really be called that, is a niche one. It will only appeal to a very select few train enthusiasts and so for those folks I'd recommend this as a nice entry into the world of train conducting. For everyone else save yourself some time, money and frustration and just say no.
Train Simulator 2013
Although it gets bogged down by some discomforting technical issues, Train Simulator 2013 is a game will appeal to a small but hungry niche gamers and hardcore trainspotters. The game offers hours of simulated railroading fun out of the box and the added Steam Workshop support means there’s always something new to do.
