Nope! This is an opportunity to make everyone a house! Why would I limit myself to just 50 or so? As long as I'm still having fun, I'll still make houses.
I will probably just do the villagers that seem nice to me. Especially ones that wouldn't ever make it on my island simply because I like another same type of villager more. Deena is a good example. I just prefer Molly every time even though I like Deena lot. Both are normal ducks. Or Whitney because I just simply prefer Freya more and even Vivian more than Whitney too even though Whitney is nice. All three are snooty wolves.
I’m selective but based on theme and not on villager appearance. I’m suuuuuuper picky about my island residents but in HHP, I kinda just use them to unlock the items I want. Lollll. So I don’t really care if they’re the most hideous looking villager but if their theme has things I want, I’d do their houses immediately.
Nah, I'm quite relaxed on which villager request I do. As long as the theme isn't one I'm burnt out on/not interested in (cafes, gyms and flowery ones) then I'll gladly build them a home. I know I could always just do my own thing on some of them, but I'd like to complete the houses as they asked for them.
