It seems to me that people are keen to ridicule Run8 and the people who are leaving Trainz to join it because they are afraid it will lead to the end of Trainz. I have played Run8 for 4-5 days now and I feel qualified enough to give you the facts, not a biased opinion. The makers of Run8 have tried to produce a realistic sim and the end result is a train sim that, to the player feels more realistic than Trainz. However, where Run8 excels is multiplayer. Run8 Multiplayer is so superior to TS12 Multiplayer there is no comparison. This goes a long way to explaining why people are turning to Run8. There is also more interaction between players in Run8 Multiplayer. Unique to Run8 is the Dispatcher's screen which is used to operate motor switches and signals on the mainline. You can do it from the comfort of the driving cab which is a plus. Now, before you all rush out and buy it here is the other side of the coin. The biggest drawback for me is nighttime. It is so dark you don,t know where a train is until you walk into it! There are way around it but in multiplayer only the host can change the time so you have to rely on a flashlight. Apart from the mainline, the switches are hand operated by standing next to them. There is no HUD so switching a yard solo is more difficult than Trainz. The final thing I want to mention is that there is no Surveyor therefore no freeware. There are routes and Locomotives in the pipeline but they will be payware. I could make further comments but they are the main points for me. My own feeling is that people who want to play multiplayer will and indeed, have moved to Run8 but very few solo players will.
Trainz has survived against Simulators with a route editor, and more than one loco... I doubt this junk will do much. Can you even make your own locos using Gmax or 3ds?
