I used to think wide vs tall was the root of the problem, and thought that wide was always better and a direct sign of a player being in the lead. Nowadays I'm not so sure, and I don't know the state of the mod in that regard. This is not an opinion I hold anymore. The root of the problem is, in my opinion, the fact that there is no catch up mechanics in the game. As in, once you're hit hard, you're out. If someone conquers half your empire you might as well just give up and quit. I'm not sure about a fix for this. I'm just trying to diagnose the disease, but I'm not certain about the cure. I'm not sure there is a "cost" to balancing the game around MP. You're talking as if SP would suffer from having MP in mind but I'm not seeing that.
