Well, I thought a lot about the maintenance service today.

"Boosting" seems a little bit strange. Best way would be, that the road gets worse and worse if no maintenance is happening until cars can only drive 50% of the highspeed maybe.

I understand the thinking behind the idea CO had, because it's an "addition" it should not influence the core game itself. But in this case I have to contradict. Every service has no influence on the city until it's reached through the milestones. You could use exactly this. Player who own snowfall can reach their milestone with the maintenance service, player who don't own snowfall don't need to care, because you just don't need to add the maintenance service to the milestones so they will never unlock it. I think taxis work this way too.

If this isn't enough - reintroduce the "ruleset" editor. An option to switch off every Service you want, perfect for people who just want to build a beautiful city without caring for the mechanics itself. I hate hearses? Turn them off!

This would be a win-win-win-Situation - and the maintenance service would make way more sense!
