Impossible, Very Unlikely, Unlikely, Maybe, Likely, Very Likely

[ForzaA]

also in peace offers, "they wont accept this" means 0% "they will accept this" means 100% there should be something in between

It used to be that you didn't get an indicator - I'm glad that now it's both mentioned, and consistent- a "maybe" option would just mean people keep spamming the same offer over and over until the AI accepts, might as well have it accept the first time then. (assuming circumstances don't change substantially)

Does anybody knows what this means?

and I'm referring specificly tho the chances. Are that chances to GET the mission or SUCCEED chances?

chance to get the mission.
