Let´s start at the beginning.
First of all, why for heaven´s sake the start of this "new" event was announced one hour after the event had started? Is it not possible any more to inform Beta players in time, not even regarding events?
Why is a "new" event not playable via the new app? I was on mobile only yesterday, confronted with an unannounced event and confused players asking me how to deal with it. It might use the mechanics of the (not very popular) Pandora event but seems more complicated (at least at first sight). Back on my computer today, even my first impression was "What the heck? I don´t have enough time to figure this .... out!" until I noticed the very clear hints. But please remember that not all Beta players are fluent in English.
However...
We haven't had a winter season event in Grepolis in a long time and players have been asking for one. Here it is!
Well, there was a seasonal event (Tyche´s Advent Calendar) leading towards Christmas & Co for years (from 2013 to 2019 to be precise) , quite long (24 days) but very simple and convenient for the busy time in December. You had not to give it much thought but still its graphics created a seasonal atmosphere, without interfering with the holidays themselves (or respective Grepolis peace times). Nothing wrong with it.
I don´t know who had the "great idea" to replace that event with a completely neutral "Tyche´s Wheel of Fortune" in 2020 with its slightly crappy graphics., which was overlapping both holidays and peace times. That caused some disappointment but many people really were speechless and shocked when, in 2021, InnoGames´ answer to that disappointment was to bring "Tyche´s Wheel of
Battle" as a "seasonal" surprise.... and all this amidst the pandemic (and while Russian troops were closing in on the borders of a neighbouring country). I don´t need Christian symbols in a game - but I would at least have expected some empathy and thought.
So, when I first read you were working on a Dionysia event, I immediately thought of spring (March/April) and maybe a replacement for the hen. It really did not strike me as a winter festival at all, and adding two candles to Dionysus´ face in the event icon and even using recyceled Christmas decorations from the 2012 Christmas feast on Olympos (^^) does not really make it so. But at least a bit of coziness is back even if it has not much to do with Dionysus.
Btw - I could swear that yesterday the announcement stated that the new event was available only on zz25. Apparently the announcement has been revised?
It is not a great idea to summarize the complete "tutorial" right at the beginning - people cannot remember it all when they finally need it. Also, again there is no wiki article ready for the event, the question mark ingame will lead to the Incantation Circle instead.
I will give feedback regarding the handling of the event later.
