I know and I said it last year before I quit this site. I know people love this game and I understand they love it for what it is, but I think many others will agree that the game needs a big update. Not just Brewster, Kappa or any of the stuff people want, but something to bring back everyone to the game. Even people like myself who played it last year wanted something "brand new" to do instead of all of these repeating events that we've played last year. I know its traditionally in AC fashion to repeat events, but even so all we got this year is just nothing but repeated events with minor updates and seasonal items.
I think from what I did restarting my 2nd island I figured out what the problem was. It was the lack of "Stuff to do" remember when Tom Nook was telling you what to do to invite KK to your island the first time. I noticed that he never tells you anything else besides then. Even back then I was hoping I would have stuff to do if he was to request a new job for me, but he never did. Which is why is "What should I do?" feature goes unused after you invited KK Slider. I think there should be more projects to do on the island so that way it gives us the motivation to keep playing and still keep making changes to our islands.
I know there is the argument that people play differently and this game was designed for mostly those who wanted freedom to do whatever they want and they can have all creativity, but for others who are not into designing play differently. Most people are not into the whole "Design" thing and just want to enjoy the island for what it is without changing it so much, but the problem is that the game encourages you keep designing and even if you got it to a 5 star rating, what else is there to do afterwards just restart and do it over again? To me I think that is just poor pacing.
