Thus far I really like the new aesthetic. I feel like the new figures will actually look like they go to the same game which was not always the case before due to varied sizes and whatnot.
For me though, the real test is the figures. I want to see them before I really pass judgement. Plus, I am much less interested in the wave 1 figures as I am in Collodi, Hamelin, Dreamer, and Kaeris. I am very interested to see what they do with these guys (although I like my own painted Collodi crew so much that I may opt out of buying new ones).
As others have intoned...you can ignore the dark & spookiness of the box art and paint them with 80s day-glow & checkers if you like (which may in fact be spookier!).
