Crap. Shouldn't the consequences be considered before you people get excited?
This comes to mind, while I like the idea and see it as interesting, the consequences should be thought of (and there are several).
Also, removing the "0 mp for passing through city tile" mechanic would mean players are less prone to extreme snaking due to no longer being able to have city highways.
I have pushed for this for a while, this is what really bothers me with cities right now, I'm not sure why people complain about snaking.
A trillion things could be done against snaking.
But really, WHY limit some players having fun with snaking just because you think its a bit silly?
The AI isn't snaking, you don't have to snake your cities, some players like to snake they're cities across the map to gain borders just the right place (me, I snake for borders or resource grabbing).
When the overland map and border-rules isn't designed around having to put your territory on every single resource, and having your borders be 1 big blob, I really think snaking is a key tactic, placing your buildings strategically, removing this choice would not serve to make a greater game since it is ignored with no problem, but it would remove the fun for players like me seeking a more interesting game, where I have more control over my kingdom, and where my choices matter.
