I usually play ACNL on my free time, which would usually be early morning (5-6 AM), afternoon (1-5 PM), or really late at night (11 PM - 2 AM). I mostly try to play at noon since the shops are still open at that time, other times would be when I do something else like talking to villagers or build my town.
Morning and afternoon. But I play Fantasy Life first then Animal crossing around 10:30am so I wouldn't have to wait for the uchi villager to wake up. Sometimes I play at night before going to bed to catch beetles.
Mid afternoon into the evening. I TT a lot so it doesn't really matter what time of day that I play because I set the clock to somewhere between 11 AM and 2 PM.
I usually play around 11am/lunchtime depending on shifts. I only play in the evenings if I'm trading or spending time with friends in-game, or there's special events going on. I mostly prefer to be in my town during the day, everything is bright and cheerful.
Depends on the day really. When I have work, I play fpr 30 minutes to water my flowers and clean up my town and such around 8am and then work for the day, and if I have a break throughout work, I can play for that amount of time (1PM-1:50PM, 10:30AM - 11 AM). Then I usually play as I relax in the afternoon or for a few hours at night (9PM-1AM). But if I have a free day, I play either the whole day or in blocked segments
During before lunchtime or early afternoon. I used to play everyday but now maybe, three times a week, mostly to check my villagers (most of them are dreamies). Though sometimes, it differs if I want to visit other towns.
I play when I get home after doing homework, usually ≈4-5 ish and I set my clock a few hours earlier so that translates to ≈2pm in game ^^; I like it better in late afternoon ehehehe
