I know I should limit my characters to 3, but every one of my towns has 4. (RIP, plot resetting at this point)
It's just that each of my towns has a theme, and each of the themes needs all 4 characters to reach its full potential and also to have enough pattern slots.
Ugh I feel ya. My main town, which is a natural town and the landscaping is complete btw, has four characters. I've wanted to change one of my villagers for the longest time but I'm too scared to even with the pattern rule because I have way too many flowers, clovers, and ground to cover. I wish I held off on that last character a little longer.
