In the last Roadmap live stream Adam talked a bit about the graphics engine upgrade TSW 2 will get soon. Namely the game will be upgraded from Unreal Engine 4.23 to 4.26. While it seems to be a minor bump, the way he described what it means for existing content is concerning in my opinion. In short, according to Adam, every single piece of content will have to be upgraded from the old engine to the new one, and every piece has to be re-released separately again. I'm concerned that this will, again, lead to an abundance of bugs, just like when the preserved collection was upgraded to TSW 2 and its then-new engine. Also, not every content will be available at the launch of Rush Hour and the upgraded TSW 2, but they will be released "over the course of around a week", which I bet right now will be much longer. I do think the very design of TSW 2 is wrong if everything has to be re-released every single time change happens to the core technology. This is not future-proof at all, and the more content is released the harder it will be to regularly upgrade everything, let alone doing it with quality results. Again, we may end up with broken routes, and we may have to wait months, again, for every single one of them to be updated and fixed. Not to mention that after the release of Rush Hour, who knows how much we'll have to wait for our existing routes to appear again in the game. This is completely unsustainable and the next time TSW is upgraded again (maybe in 2022), who knows what content will be kept, if any at all. For me as a player this makes no sense. I'd like to have a unified platform for which I can safely buy content, knowing it will be maintained and supported for many years to come (look at Train Simulator). Not re-released, broken, fixed, and re-released again like a vicious cycle. After a while, there will be simply too much content to handle like this. I'm getting more and more wary of the Rush Hour release, again not knowing what will happen, what will disappear or reappear in a buggy state. This just erodes my confidence to buy anything for the game.
