Though the thread is permeated by negativity, I'd have to agree with all of the points stated above. CiM2's mid-air roads and expressways have support columns , so why not metros and monorails? And not having realistic stations (in comparison to CiM1) really bothers me. As I stated in Steam's CiM2 threads, it's like passengers are using warp plates to enter/exit to/from train platforms/streets.
If CO has to eliminate the option of allowing freedom of setting heights for metros and monorails in order to implement the building of structures (stations and stairs), then I'm all for it. As long as the implementation is pleasing to the majority then forget the "freedom of height".
It seems that CO enacted a rule of interface design which reads like this: "Whenever you're designing software or creating a user interface implementation, you have the choice of a) setting options [in this case, allowing players choices between freedom of height regarding track building, or tying tracks down to specific levels, like in CiM1], or b) giving users an intelligent default [in this case, the freedom of height design options in CiM2, which has constantly been protested, thus making the chosen intelligent default lacking]. It's usually better to set intelligent defaults for end users because it makes the interface more user friendly [apparently because CiM2's interface is much more complicated than CiM1's, CO decided that the freedom of height interface for track building was the best choice because it seemed the least complicated, especially with the variable terrain and heights found on the different maps]. Yes, setting intelligent defaults takes power away from the user [thank God for modders, because they work on adding mods, thus giving end users more options as to how to play the games], but it makes everything easier, and if your default is INTELLIGENT [capitalized for emphasis] then it won't matter."
The problem is the intelligent default that CO used when designing CiM2's interface for end-user track designs is that they eliminated one of the few functions that almost no one complained about regarding rail transit design, which were the limited metro height levels found in CiM1. Yes, elevated tracks were very close to the ground in CiM1, but they had support columns over the streets, highways, and bodies of water, and more importantly - realistic stations with entrances and exits. The underground stations with stairs are a LOT more eye-pleasing and functionally sound compared to CiM2's implementation. I spent a lot of time watching as multiple metro routes arrived/departed at/from the stations, with public address system announcements.
For those who are upset over the negative tone of this thread, all that I've stated above are the reasons why many CiM2 players are extremely upset. Busses, trams and trackless trolleys have their uses and appeal, but metro route building requires the most work, the most cash and (if planned correctly) the quickest way to generate revenue and thus eliminate debt. The problem again is that CO fixed a problem that was never a problem.
