Currently, campaign missions can only be replayed via Ikora's Meditations, and only certain ones are available each week. They aren't anywhere near their original difficulty and you can only play them once on each character per week. Strikes are only accessible via the playlists and you can't choose which one. Adventures are the same as the campaign missions except with the location NPCs. World Quests cannot be replayed AT ALL. All of these activities need to be accessible both in-world and directly through the map, to be played through whenever we want, at their original difficulties, and reward glimmer and xp for the time invested in playing through them again. BONUSES: 1) Difficulties - Easy, Normal, Heroic, and Prestige. Heroic will match the power level or Heroic strikes or Ikora's Meditations, Prestige will always be at max power level and reward cool stuff on completion, and Easy has lowest light level possible and only rewards glimmer and XP. 2) Mission Challenges - A speedrun challenge, a "no deaths" challenge, and some other third challenge for each campaign mission. Doing all of each type of challenge across the campaign would reward players with something. 3) Hidden Areas
