Before being too critical of Train Fever in comparison with Cities Skylines consider this:
Skylines has an 18x18km map size (10×10 playable, with unlock mod), which has an overall base grid resolution of 1080×1080. Divided down, that means each cell of the map is 16.666m. (When playing, it appears to selectively refine where you build to create minor embankments and such, but the base terrain is still limited to that)
Train Fever by comparison, has a 16x16km map size (fully playable), which has an overall base grid resolution of (I believe) 16000×16000. Divided down, that’s a cell size of 1m. This means that for every single grid cell in Skylines, Train Fever fits in roughly 278x as much terrain detail!
Considering that, I’m still staggered that Train Fever runs as well as it does! A 256-million-square piece of geometry is a hell of thing to get to display in realtime, and that’s not considering all the houses, roads, vehicles, people, etc. I know they use some very clever streaming LOD tech to not literally display that many polys, but all the detail is there to be looked at when you want to, and I very rarely spot any hint of LOD pop-in while it does it.
I still think Train Fever is an incredible achievement, and I suspect I’ll still be coming back to it long after I’ve had my fill of Cities Skylines 🙂
