"unchangeable" is dangerous. You should never force movement without some sort of alternative. For example, the shortest route out of the territory is 4 turns, so then the player should be able to pick to which location those 4 turns are going to be spent. If it is unchangeable, players are going to become frustrated by it. heck Denryu's already frustrated by it, and it isn't even implemented. Many older games auto-shove units to the nearest border, which I feel is a poor way of doing it as they tend to get stuck on sides of the map they cannot get home from.
I often say "if it isn't broke, don't fix it" (or at least I think it, I don't usually say it unless its in the voice of Clockworth from beauty and the beast) but in this case it is broken. We should try to think of a better way of managing it, rather than default to the way its been done since the 90s
Yeah, as I said in my second post there's a
much better way of doing. But the point is what we have now is not at all satisfactory, and it's very easy to fix.
I wouldn't say a VEEEERY hefty diplo penalty, unless your violating with like 1000 armored troops. Everybody spies on everybody else. Its the way of things. Perhaps just a *sorta hefty diplomacy penalty.
Yes, unit-based degree is already in my proposal, just not phrased very well. Also, some factions should be more protective of their borders than others, and your diplo state should affect the aggrevation factor: i.e. a couple of British soldiers caught on US soil w/o a passport would cause a
lot less of a stir than an equal number of equally-armed North Korean soldeirs.
