I tried installing Windows 8 touchscreen device. It works mostly fine, but there are some issues, mostly expected stuff:
- UI elements are too small, even for my 13" screen. I know I can increase font size (and I did), but it doesn't increase size of many UI elements (window header buttons, toolbar...). I know I can go fullcreen and reduce the resolution, but I would have to reduce the resolution to something like 800*450 to be really comfortable to play.
- I can't figure out how to activate the toolbar menus (holding tap translates to right click).
- With rail/road construction tools enabled, it becomes impossible to scroll around, because dragging finger around builds the road/rail instead (perhaps the two finger gesture could work here nicely).
I was actually quite surprised that finger scrolling and pinch-to-zoom gesture works at all (most games not specifically programmed for touchscreens have issues here).
