Some of these roads look harmless until you meet another vehicle halfway through a bend. Then you're watching the mirrors, easing off the throttle, and hoping there's enough room to squeeze past. The mountain sections are particularly good at keeping you alert. Rainy weather makes things even more awkward, especially when visibility starts dropping.
Unlimited money is already unlocked in this version, so I can spend more time fiddling with the buses instead of saving up for every upgrade. Changing the paint, trying different wheels, and adjusting the little cabin details is surprisingly enjoyable. I usually put some music on, pick a route, and see where the road takes me.
