Thanks for all the suggestions! I think there are many good ones. Sorry for the wall of text, I tried to answer everyone!
"The wheels on the bus (and other vehicles) certainly don't go round and round (such a small thing but it was missed when animations for other aspects like doors opening and passenger actually getting on the were added)"
This might be impossible to add at this point, we have put most of the detail on top of things because usually the camera sees the tops closely.
"All vehicles seem to have headlights on all the time."
This was a choice we made, that's how headlights have to be used in Finland. It's illegal to drive without your headlights on.
"No way to edit/delete profiles (without editing config files) and editing the selected ones just adds a new profile."
I will add this issue to our fix lists and we will see what can be done.
"The tutorial doesn't feel as intuitive as before."
We did a lot of work with the tutorial, I think it's one of the hardest things to make in any game. Could you specify what feels worst in the tutorial?
"It is possible to scroll the environment by holding down control but an option to do that without in the games settings would be welcome."
Edge scrolling will be added in the next update within a few days.
"Menu interface doesn't feel as polished as before."
This might be because CiM2 is so different from the first game that we decided to re-do the whole menu and not save everything from the old one. The interface you see is actually our third version, we really put a lot of effort in it, but I do admit it's not perfect. If you have some specific issues, I'll see what we can do!
"Not possible to register the game for steam users as they don't have a CD key as such."
This is an issue with Steam currently and we can't do anything about it, I'm very sorry. As soon as it's resolved, we will make a post. I hope it's soon!
"Doesn't seem possible to connect to any of the online game sessions."
There's an issue with modem settings that we are looking into just now. An update will be available soon!
"Keep the thing with Rightlick + Mouse Wheel = fine rotation but add hotkeys for the 45° rotation so rightclick can be used to close the build menu (like every other game does)."
The hotkeys are currently not in our plans, but I'll look into adding them.
"As people said before: The roads shouldn't appear in the underground view. In addition I'd make the grid thinner and (maybe) not casting shadows."
I'm currently planning a fix for the underground view, these are good suggestions!
"Add a key for closing all open windows."
Can be done, I'll add this to my list.
"Rightclicking a text link in one of the menus should center the camera on the clicked object so you don't need to open another menu."
Do you mean like choosing a depot or a vehicle?
"Since buildings in the editor are categorized into themes, why not add painting themes to the map like you paint price zones (but with a smaller brush) in order to influence the auto building generation."
This is an interesting idea, it's not our priority at the moment, but I'll definitely add this to my wish list.
"I don't know if there's a way to hide the influence circles from the stations but you should be able to hide them. IMO coloring the buildings in CIM1 was a better solution."
The catchment area circles only show when the station is chosen and when stations are built close to it.
"I'm having trouble distinguishing between the light green and the medium green color of the ticket prices."
The shades are probably too similar, this will be fixed!
"I'm not too far into the game but let's say you want different times on different days on one route's timetable - do you have to create a new route and select all the stations again? If yes, there should be a way to clone a route or add multiple entries (start time, end time, interval, selected days) to one timetable. Another option would be to enter these values for each day independently (so you'd see the form elements exactly four times)."
I'm not sure if I understand correctly, but there's a "copy from line X" feature so you can use the same timetables on many lines. If you want one line to act differently at different times, the timetables will handle that, you can customize them and freely add starting and ending time and on what days to use a timetable.
"It's great that you can center the camera on a vehicle, even if it moves. However, if you zoom in and tilt the camera, the vehicle is out of focus. This should be fixed or better: give us the ability to pan the camera while the camera follows the vehicle (great for movie-making)."
I'll look into this issue. Just to make sure I understand you, you want to "ride the vehicle" and look around at the same time?
"A key to snap roads into 45° angles at intersections would be useful if there isn't a way to do this already."
I'm not sure if this can be done, it might be very deep in the game logic, but I'll consult our programmer!
"It'd be nice to access the options menu from the editor."
It definitely would ;P This is a bug and will be fixed.
"Camera needs object collision appied as it currently colides though everything."
I feel this might make moving the camera too hard, with many high buildings it would be tricky to navigate.
"Alt+Tab causes trees to morph into cardboard cut-outs."
This is a bug and will be fixed.
"Timetable interface needs improving as it feels like using Excel (not fun)."
I'll see what we can do.
"Screen gets cluttered with windows to easily."
The close all windows button might help with this, it's coming.
"Selecting a cim and pressing the down key several times after the lowest camera pan level causes the camera to lock vertically."
This seems like a bug, I have to try if I can make it happen and determine what causes it.
"Depot, vehicle, stop upgrades would be a great addition in a patch, rather than having to delete and build from scratch."
Currently you can upgrade stops and depots, just choose the type you want in the build menu and place it on top of the existing stop. The closest thing to upgrading vehicles would be to buy new ones to the depot and sell the old ones, the new vehicles will automatically be used as soon as a line demands a vehicle.
"I feel there should be some sort of rule that determines whether a new vehicle gets sent on a route or whether a vehicle finishing up its current route starts again. This should have something to do with the conditio nof the vehicle ie. if vehicle is under x% condition, send new vehicle if one is available in depot. (This only applies when setting first and last stop the same on a route and having the depot on a loop nearby)"
I'm not sure if I understand you, now the game works so that when a vehicle is in poor condition, it will finish the route and go to the depot and a new one will be sent. There's might be a bug, but I've never seen any with this feature.
"Trains should have reverse at end of line feature, having to build a loop is ridiculous, especially when building elevated railways in a city"
You can also use another depot to reverse the train.
"Depots should not have to be included in a route. They should be placed independently and vehicles should have service intervals or require service when they get below a certain percentage. When this percentage is reached the vehicle calls at the depot the next time it passes through."
The depot system was a design choice we made very early on. We felt having lines connected to specific depots gives the game more depth and a tactical element it wouldn't have with individual depots.
