All of the seasons their own charm, and I definitely like fall/winter way more in acnl than in real life lol. Spring is probably my favourite though! I just love the cherry blossoms, it makes everything so pretty!
I like summer the most. Mostly because of the bugs and fish there, I like the thrill of tarantula, scorpion and beetle hunting, finding fish and enjoying the nice feel of the dark green tree and ground. Autumn is also a good season, the nice colors especially at mid November. Winter is okay, I guess. Spring is kinda okay, I like the cherry blossoms there. :3
I really love spring in Animal Crossing - seeing trees becoming a nice pink color and its leaves fluttering in the wind as you walk around your town gives the season a magical, dream-like feel.
I also like winter, even if I can't really enjoy it, since none of the patterns I have match with the environment.
Oh shoot I thought this was asking in general and forgot I was in the ACNL discussion section... I chose winter cuz I like winter IRL but I've never experienced winter in ACNL cuz I had quit before that. I'd have to go with summer for ACNL. <3
