First of all: Relax, it's the holidays and people don't have as much time for RPing or straight up can't as they go visit friends and family. Now.

Crossover and self-insertion games are nothing new or uncommon and this one's hardly perfect or anywhere near close as seen with the discussion of superfluous or poorly thought out elements. I think you might just be overly attached to it like someone's overly attached to the first game they ever played and I suggest learning to move on and accept that sometimes (an overwhelming majority of times) games die, otherwise you might find yourself beating the same dead horse with the same stick over and over again, I've seen it before and there's nothing sadder than a roleplayer that just can't move on from a character or game instead of coming up with new ideas.
