Remember the big updates we had? My fav was “Ancient Greece” you move forward as lined up quests and puzzles you had to solve. Follows up different sections like Medusa: hide in shadows or she sees you and you restart the puzzlle. That-was-crazy!
You got unique quest items even though you only did one section, a tool to progress next level but… the tool is also had great look, like “Feather of Pegasus”. That was making the game sections interesting while the game goes deeper and harder.
I totally agree with you @Regi this could be tons of fun. Even as a concept of it sounds fun.
Totally supporting this idea!
Also @Rubens mentioned the Awards System Expansion, it might implement completing sectionss of events like this. Agree?
