Heya!
I like this! It could be awesome if the system would save every cutscene that we have done in a menu in the Main Menu called "Echo" like you said.
Would work like this:
For every character you have a menu of the cutscenes you've unlocked. Doing this will solve the problem of which of your character show in the cutscene.
Every cutscene has a city-state to indicate it. As for now, it could be required to show only one of the main city-states where you create your character, but maybe in the future will be implemented cutscenes for quests in other city-states, so I thought to leave it there.
Locked cutscenes will be displayed as -----------.
You have first to select one of the lists (LiLo, Ul'dah, Gridania,...) before selecting a video.
How you find this? Could be a good implementation, a scrap or can be bettered?
Here's the screenshot of the idea:
Clicky!
See ya!
