I have two Ideas, one for the birthday party event.1.a quest for an event during the birthday party (if you don’t make it in time you could use it for next year). A reward would be party emote where you dance around then throw confetti or you could make it to where when you ware the party hat you get the choice to do this emote.2.a quest list to show what quests you have done and how you did them In journal form for example: I did… or me and john killed… (you could get to it by a tab in your quest page in book ).
interestin idea on the second one. I would also like to see a log of missions you have done. However dont thank the the journal on who what when and why would work, I do believe there should be a log that the ones you have completed are in red and the ones that arent are the basic yellow. Also for the quest page, you should be able to tell the difference from the main quest and the sidequests, maybe main quests in blue, or possible to limit the amount of space in your quest book, maybe being able to set aside quests in a side bar for later.
