Seeing as how I've recently started playing SC4 again, I have a few questions (and keep in mind, I only have the original, not the expansion pack):
How exactly do you place public transport stations (especially subways) to be effective? Every time I try setting up public transport in my cities, I end up with constant ratings of 0-10% usage, regardless of how many I have, or where they're placed. Trains are about the only one I ever see working decently (reaching as high as 25%). Also, assuming I can get those things working, is it worthwhile to have multiple forms of public transport in the city? (buses, train, subway, etc)?
Also, how do you use freight train stations anyways? I've never been able to get them to work, so I assume you have to place them in certain places to be effective, but where?
The public attraction things (like parks, flower gardens, etc) what exactly do they affect? (land value, etc) Would it be just as worthwhile (and less costly) to just have a big patch of trees? For that matter, do patches of trees on unzoned land do anything?
Does planting trees on buildings (either public buildings, or on zoned land) do anything? Are its effects the same as being near unzoned land with trees?
Does the type of zone you place (low/mid/high density) have any effect on things BESIDES simply dictating what levels of buildings can be placed? (e.g., is low density residential prone to higher land values than high-density, even if single houses are all that's built?)
Gifts (like the radio tower and farmers market), do they have any real effects? Or are they just for show?
That's all I can think of for now. Thanks in advance for answers.
