Right now, most of my campaigns (there's really few of them that I did for fun on MC2X) only use base maps (as in the basic terrain), very little story (some with none), few abl/warrior brain stuff, etc. Not saying I can't post them, but most of the campaigns I've spent literally days (even hours) and none really serious/complete.
I do realize that MCO is mainly mechs only but when I put no mechs or aircraft with no logistics (like 1st Carver 5 mission), the mission simply failed. I put a single dozer in that mission where I also put a few wreckages in the map for salvaging. The dozer has a pilot and pbrain but does not show up at all, signaling failed mission. The goal of that mission was to capture the enemy mechs and then destroy the enemy base. This also happened a few other times in missions, where once, I created a convoy with two Sha Yu's. The Sharks/Sha Yu's spawned under player control but the convoy was completely gone. Basically vehicles can't be under player control, they just disappear.
Lets see, I have one campaign about some random stuff (literally, one missions about the North Korean dictatorship and then the next one is about how Tangoblue was created. Tangoblue is a special high heat ball of homing doom from mc2x, if it follows a mech, chances are you're going to lose it. Maybe Fafnir's are lucky.)
I have made one campaign about MW4 Mercs but most missions/contracts were heavily modified. It's based off MC2X though, so it wouldn't work on MCO.
I have made one final campaign about a so-called 'Death Clan' and it basically was a test of my modding skills. I learned a bunch of things from that campaign, like abl file editing, purchase file editing, and difficulty. My earlier campaigns had mc2xattack brains, no music, easy difficulty especially starting out with near infinite cash and enemies with crap equipment. This campaign actually is one that's considerably good.
Right now, I'm just testing what I could do in MCO for fun, and I installed MCO to two different platforms. One for gaming and one simply for completely changing maps. I deleted all enemies, objectives, and everything that needed to be deleted in a few of the modding platform. So far, the only errors that I've encountered while modding the campaigns (BTW I'm using Exodus, MW2 Mercs, and Carver 5's maps and if I ever release these, I give the MCO team credit for making the map in the first place.) is the weird fit file error that I screwed up somehow and the vehicle 'Houdini' bug. This campaign is still in progress.
If you want or any other's want, I could release a campaign or two, but I'm going to have to learn how to in the first place.

I've no problems with that. Please note that I've not much experience from modding and most of it comes from help from the Mechcommander community. I've got to say though Magic (and Wolfman-x and the rest of MCO team) thanks for providing a mod in the first place, all of them are awesome.
