CIM2 is a very interesting game, if you're into LOTS of micro-micro-micro-management. And I mean, really micro, as in adjusting timetables (down to 15 minutes steps IIRC) for all your lines and all weekdays.
It has some slightly annoying stuff going on in UI and controls, like when you have a neighborhood crowded with lines it's hard to understand what is what, but nothing really serious, and I guess it's kind of inevitable.
Just in case, keep in mind that it has basically zero city building aspects. You can create roads, but then buildings around them will pop up automatically.
And I guess it really help if you're used to.. erm... US/UK/northern-central-EU hours, because I'm Italian and I just can't get the grip of how "ROW" rush hours work... :'(
Also I wake up at around 11 so fuck all that stuff like morning rush hour at 7-8, what is that, why you people want to live in the shadow, are you vampires? DO YOU LIKE TWILIGHT OR SOMETHING?
Pleasure is all mine! It was the same for me, and now I'm finally installing it, so it better be good as people say!
