@rowey the popup should have some way of organizing the missions
either have two lists, first the "group" and then the mission, for example: first you pick between "Aeon Campaign" "UEF Campaign" "Cybran Campaign" "FAF Campaign" "Seraphim Campaign" or "Special Missions," and then based on your choice, it lists those missions in a second list
or just have one scrollable list, but the list itself has the missions organized by category. So instead of just listing the names of the maps, it would be something like:
I don't know if the "difficulty" setting is still causing problems (defaulting players to a hard setting, then they don't know why the campaign missions are so rough). If it is, consider having that be part of the popup. So every time you're going to launch a mission it has the difficulty showing.
Also, is it possible to track/show on the dropdown mission list whether the player has completed each campaign mission? It would be nice if it showed that, so people would know which missions they haven't done before. That would be a subtle encouragement to try out the various missions. Or even to show the difficulty setting that people finished it on. Which would be an encouragement to try harder difficulty settings for the missions.
