1. Start date - 1985 is optimal. Players should not start with monorails, it's not in the 'long-run' style, but 30 years with slow trains as it works now it's too much and wasting player's time.
2. End date - 2090 is reasonable. New players should be able to win it too, right now it's painful to see how a lot of effort goes nowhere and the players who work there for hours can't score any points. Maybe we could change the date to 2080, since the goal is lower than on #5.
3. Max station and train length - 14 is nice to try. 20TL is something most of N-Ice players got used to (servers #3 and #5), but it's worth to try new setting and new possible designs for a long run. Reduced load on a server\clients is a key thing too.
4. Max train number - 500 and not less. With the same production rate we will need 50-60% more trains to fill the gap, because train length goes from 23 to 14. Later we can adjust this number further.
5. Max R.V. number - 250, why not. It's a minor change, since IMHO road vehicles aren't that useful.
6. New goal value? No!5bil goal - It's not an 'N-Ice long-run server'™. Game will end too soon, since even with 10bil goal one person did it in 35 years.
15bil goal - Some players already complained that 15bil on #5 is too high for them. IMHO 15bil and 10bil servers in da house is nice, people can choose what they prefer. Also, since we're lowering the TL, it should decrease the average income too.
And implement it as soon as possible, please
