Cabal of Crazed Commanders

[Terath]

Unfortunately, from my limited knowledge of Warband coding, it's not that easy. You'll have to get someone else for the specifics, but I'm 95% sure that Singleplayer coding is very different from Multiplayer.

Leaving that aside, I like this idea. I like it a lot. Regarding how you're thinking of making it work, I think there's one improvement to make. You've said that there should be big, open maps made for a mode like this. I think, however, that it would be better if maps for such a mode would be randomly generated. If you have a couple of fixed maps, a gamemode like this would quickly turn into standard NI gameplay of huddling in a set corner, because everyone already played that map countless of times and knows that's the spot that the easiest to defend. A random map, however, would force you to consider where to go every time the map changes.

I said above that a commander battle against bots would likely be impossible. Porting over something like Captain Coop, however, is not.
For those of you who haven't played With Fire and Sword, Captain Coop is a multiplayer gamemode that allows every player to take along up to 6 bots, and fight together against bots, NI style. Bots get progressively harder, but your own bots and the equipment you can bring also get stronger as you get further in. I think this would add nicely to NI, and I'd certainly support such a change.

Oh.
To not being able to port over the code from singleplayer, I am sad. It fits near perfectly. However..
I have never played Fire & Sword. I do not know what it is about, how it works, anything along those lines. If there is a solution in there somewhere to the issue at hand, not being able to port the code over, then so be it, use the Fire & Sword code.
To the maps, I completely agree. Now that I see that it would just be camping with a lot more people, I think using randomly generated maps would be a great way to make it impossible to camp in one place until the wave is over.
Captain Coop sounds hilariously fun, so I'm glad it'll fit NI quite nicely. I'd absolutely adore this gamemode if it were to come out.
