I am having a few thoughts on how I would like to see SimRail expand in terms of geographical and route content. First and foremost, I am sure SimRail team already has some solid plans as to what they want to do with the sim, and I also understand all of this is driven by the realities of running a business. It is also very early in the game lifecycle. But I just wanted to share and hopefully spark some interesting discussion and ideas about what's next for this nice looking sim so far!
Often when it comes to upcoming simulation content, users from all over the world usually wish to "pull the cover' towards them: see trains and routes of their own homeplace. This is a very human thing to do and I'm no stranger to it. However, I do not think this is the most ideal expansion strategy for a sim such as SimRail, which puts greater emphasis on the infrastructure side of things than previous simulation titles.
Poland offers quite an interesting and diverse railway experience, and I would dearly like to see the development team capitalise on it and expand from the current lines, instead of picking random bits elsewhere. I'm thinking connecting the current routes we have to Wrocław or Kraków (and the beautiful Tatra mountains?), or up north to Gdansk. My point being: when considering new content to develop after consolidating what you have, would it not be better to implement topologically connected regions instead of "one-off", isolated network from what is already there? Too many times has train simulation content not made sense geographically.
For international expansion, we are lucky to have Poland being a geographically quite central place in Europe, connected to Germany and its now well known railways infrastructure and rolling stock in the simulation world, as well as lesser known rail networks to the south. I'm thinking about Czech and Slovak railways (and further down to Austria), both with very interesting scenery, rolling stock, and railway infrastructure (MIREL, ...). The point above stands: connect instead of isolate, while still allowing to discover new rail networks and its associated unique services (cross border, multi system operations, EC/EN/NJ trains, etc.).
Incidentally, it's increasingly been my philosophy of travelling: see what's immediately next door and expanding from there, instead of making big leaps to far, not necessarily connected places. Often the discoveries are equally as interesting! I am excited either way to see what's next.
