I guess they'll patch it up at some point, but until then, it's not ready for release, and hardly playable. Laying tracks is a nightmare, editing existing lines (or even checking their route) is near impossible, there's no indication at all of passenger traffic (what lines they go on, when, origins, destinations), and worst of all, no autosave, and the game crashes relatively often. As usual with paradox - great ideas, poor execution.
Upsides: Very nice graphics; Despite the twisted time-space issue, the time-of-day feature fundamentally changes gameplay and adds a whole new dimension, adding very much to the game experience, such dynamics is very enticing to keep monitoring and correcting; The zones and tickets feature is also nice, but does not come to not very meaningful experience in game play, probably since the whole economy system is lacking - there's hardly any clear connection between financial decisions (pricing, wages, scheduling) and revenue.
