I'm pretty sure steam locos didn't have a head up display giving the driver and fireman 100 points everytime they coupled to a wagon.
Maybe I haven't read up enough on the subject
A more realistic approach is to give them a good rollicking after they finish their run and have broken various railway rules.. much as it does currently, but could maybe do with some more detail.
I would also dispute that just because people don't want to be scored, they want free roam. I don't want scoring, but I never use freeroam unless I'm testing.
I want a task, I want objectives, I want some prototypical railway operations to complete.
I'm just not interested in having the mystical sky monkeys pasting a number onto my eyeballs everytime I do something they deem worthy, and then having that number compared to "Dave and Ted" who are "teh awesomest" because they used 1lb less than coal than we did on the same run last week.
That doesn't mean it's a bad thing, and as it's totally optional, as long as they don't
replace half the scenarios that come with addons with career scenarios then nothing's lost by having it.
I just think realism is a poor arguement.
