Below is the summarized set of responses from people, I have tweaked the wording and merged some to simplify the responses.
Responses for What would you change about the event and why (+5 plushies)
===============================================================
Generally people have commented that Chewett should have more help, and do less
Note by Chew: Lol
Some suggested making the celebration shorter than 17 days, some suggested making it longer. Some also commented it should happen more frequently
One comment was relating to being able to get medals without attending the Awards Ceremony
Note by Chew: As discussed with Mur, this is by design and we were present for multiple days and timezones
Some people disliked the plushie rain, some people really liked it
Note by Chew: This probably sits in the right spot, but further opinions are welcome
People really liked the A25 mist/rain events and wanted more
People suggested adding a leaderboard for plushies
Note by Chew: This sounds like a nice little idea
Generally people wanted more group/story type events, and land type events where collobration is key
Lots of very positive comments here (saying they wouldn't change anything)
Responses for What do you think worked well about the event and why (+5 plushies)
===============================================================
The daily scene location was great, lots of really positive comments
Mist events where highly rated by many people (many of the responses mentioned it)
Seeing locked scenes and old friends was highly rated by many
Contacting old players to see how they are/drawing them back
Note by Chew: We need to improve this going forward so its not me manually messaging people!
Responses for What other ideas could you suggest to make next year's celebration even better? (+5 plushies)
===============================================================
More group party games
Digging up old history
Cooking quests
More mist co-op events (lots of comments about this), people really liked the "changing realm" stuff
New player friendly events like the Easter Egg Hunt
Note by Chew: This should run yearly, Many thanks @Fyrd Argentus
Having a more clear daily host would be ideal
Note by Chew: I want to move back towards having "day hosts" and giving them a lot more powers but this year I was more busy with Life.
Contacting old players again, marketing emails, etc
Note by Chew: I did a lot of this myself, but we need to improve this for next year as it takes masses of my time
Plan some official "Realm changing" events like the mist.
Note by Chew: I plan to do these kind of things more and more now, the Mist event is a good example and I hope to finish this shortly
Responses for What other events would you want run during the birthday? (+5 plushies)
===============================================================
Lots of comments about more mist type lore events
Some ideas about giving players usable items such as shovels/etc, and special items and gifts
Simple quests that give small rewards (such as plushies)
Lots of comments about cooperative land events (lots of comments about mist/group type events)
More MDScript events
Trivia/puzzle quests
Responses for Any other comments about the event (+5 plushies)
===============================================================
Plushies raining down had lots of positive comments, and people really liked the increase later on
Lots of different events was generally favourable
Someone wanted more quests, and suggested the reason people weren't running quests was because they didn't know what was allowed
Note by Chew: Anything really, just message me next time
There was a comment that the birthday was "hard to do from the US".
Note by Chew: I don't really know what this means because typically we run events in good EU/US timezones. I think generally we have issues with people in GMT+8 -> GMT+14. Whoever said this can you message me if you want to explain further please
Lots of good comments about the work of the GM's, quest makers, and A25 team.
