Some interesting comments here guys and some really thought provoking discussion. To be honest the debate fails to get very far in my mind, I have a hard time imagining any gamer buying Railworks unless they either currently have or at least have had at some point, an active interest in railways.
No matter how simple you make it, no matter how many control options you provide, no matter how well you market, if the end-user doesn't like trains then they aren't going to buy it! A train simulator is exactly what the title says, you can't make it mass-appeal and you can't use it for any other purpose except maybe route building, but if you did buy it to route build then you'd have to be interested in railways to want to build a route to run trains on!
The world of trains is a funny one. Viewed by many of the population as the number one, bar none, geekiest, nerdiest, most cringeworthy hobby of all time yet amazingly, there are a staggering number of people out there, particularly in the UK where railways are everwhere, who are interested. Although understandably many of them keep their dark secret locked deep underground and firmly in the closet! or on the internet hidden behind anonymous usernames!
Bearing all that in mind, I can only see one conclusion. Proper "simmers" and rail enthusiast types are the only viable customerbase for the long term and satisfying those people is where the focus and attention should be made (in my opinion). Attempts to broaden appeal will almost certainly fall foul of barrier numero uno, you have to be interested in trains to buy it.
The good news is that proper rail simmers/enthusiasts are in abundence despite the aforementioned shame of it! Although a niche, it is also an incredibly popular interest all around the globe and so I am totally confident that RSC and other devs have no worries about running out of customers. By their very natures, simmers and rail enthusiasts will always crave better and better products and more and more realism. They will also be willing to pay for it. The future is bright
