If I'm waiting for shops to open up or for an event to happen (for example a certain time that a neighbor is visiting) I always just play Desert Island Escape now.
I've been spending a lot of my spare time at the island lately. If it's night, I go hunting for beetles. If it's still early in the day, I just earn a ton of medals doing tours. Not much for me to do at my villages at the moment. Occasionally I'll drive myself crazy playing that evil Puzzle League game. That's about it.
I'll usually go around and talk to all my villagers a lot or visit their houses, or I'll go to the island to catch a bunch of rare beetles to sell to re-tail (gotta get those bells, amiright?) I would like to be able to start landscaping, but I can't until I get all my dreamies to move in so I know where their houses will be >~< Sometimes I will just sit and pass the time by playing puzzle league to get meow coupons, it's fun and kinda productive!
I usually kill time decorating and playing puzzle ligue or just listen to some kk song in loop -.-
anyway it's for kill time in real life that I play animal crossing ^^
