Most Far Cry 2 activity on youtube and forum-sites like this, is editor-related. Ubisoft are aware of this, ofc, and therefor I believe having an editor or not is not an option. I think they want to make the story/singleplayer-mode be more attractive and exciting than previous games, but I still think their main concern would be to pleas all their potential buyers, which consists of a whole lot of hardcore editor-fans.
Hopefully, I'm right
I'll be picking up this game for sure! Can't wait. I liked the FC2 story-mode, and I bet the FC3 story-mode will be even better. And guys, they have confirmed instant-travel, which I believe would be something like the helicopter picking you up, and dropping you off at the preferred location in Just Cause 2. So I guess we won't have to drive 50 miles, only to realize you forgot to chose the right weapons for the mission, and then you would have to run for 10 min to find a arms-dealer, and then go back to the mission.
Anyways, my PSN is;
metallicamaniac
and i might use another called tallicamaniac, if they chose to set a max amount of maps made by each player, like in FC2.
