I hope I'll manage to show my point of view clearly on this.
I have a feeling that if we make a function where x is a cost of an item, and y is benefit the graph usually will be more less linear.
I would like to have this graph much more expotential. I'll explain this on the example below (numbers made up):
Linear function:
skateboard
cost: 250
speed: 5
bicycle
cost: 500
speed: 10
motorcycle
cost: 2000
speed: 40
etc.
Expotential function:
skateboard
cost: 250
speed: 5
bicycle
cost: 1000
speed: 10
motorcycle
cost: 4000
speed: 40
etc.
Does it make any sense?
The idea here is to keep benefits growing linearly , and costs expotentially.
Just to be clear, I don't really want to mess with vehicles and other stuff we already have, just thinking about adding some better things (better cars, buildings etc.) which won't be much better, but their cost will be much higher (building cost, not operating cost).
The goal here is to let some wealthy chars/societies advance to the next level - much more difficult level, which makes them just a little bit more powerful. I see to many chars that kind of "finished" the game, and then they quit.
Some ideas to achive that:
Fancy builidings (made by upgrading existing ones)
New ships
New cars (not sport cars, but some useful ones)
Better engines (extremely complicated)
More uses for gold and gems
Some really longterm and difficult projects e.g. Huge Tombs like ancient piramids (10 tons of stone, and few other resources, 1000 days to finish it
Some new alloys, or composites (reinforced concrete? - buildings will need steel! )
Better quality and more expensive items
There is a point when a player has everything he can in the game and then doing anything became pointless. Don't let them get there so easily!
