F151 (Laurent) road-building is pretty fast for me (again, I always put LOTS of kapital in it but even then, 12 squares including 2 hills and a mountain in one turn, it seems a lot).
Mark said: But part of the reason its so fast at 30% road building and above is that 30% is an Enormous amount of resources to put in roads.
What real 'civ' spends more than a few percent of revenues on road-building? There are so many other competing demands...
Laurent said: Yes, but in the game, which is not a simulation, it seems weird. There are so many things the player doesn't see, that roads, which are something he sees (and not in a lost menu but on the map), should have more importance than in real-life.
Anyway, players need feedback on how much money to put in the road-building (so I don't put 30% where 5% is needed), and they can stage it over several turns.
My suggestion, maybe put in an arbitrary delay for road building so it happens over time. This would also prevent flash-building of roads during an invasion. Maybe an automatic 2-turn delay between order and building? [low D7.1]
