I have 2 towns, I think it's worth it if you have more than 10 dreamies. Plus I've cycled a bit to help others which i liked. I have one themed town and one un themed. I think of it as the best of both worlds literately
Just one town here. Maybe one day in the future I'll get a second, but for now I'm happy with one. I didn't even think people would buy a second copy of the game just for cycling, but it seems like it's a pretty popular practice here!
Right now two, I have a 3rd copy for my use of cycling soon. Me becoming so addicted to this game makes me want a 4th game so I can make a Zen Themed town with Zen Themed villagers.
I got my first town on my birthday in July last year. Later in August I decided to get the XL 3DS because I liked the bigger screen. I also decided on a second copy to cycle. I ran a cycling thread with another user on a different forum for awhile before my schedule just became too crazy. I still continued to cycle villagers to giveaway though till the end of February this year.
I really enjoyed cycling and helping tons of people get some of their dream villagers. However, it did take up a huge part of my time and I honestly didn't get to spend much time on my main town at all because of it. I decided this year to reset my second town for good, find a lovely layout, and keep villagers I liked in it. I'm happy I did because I do spend more time actually playing the game for my own amusement now. It's also nice to have a second town that I can sort of design much differently than my first which is asian themed.
I don't find it takes more time. I usually start by running around and checking to make sure no one pings in either towns to move. After that I choose which town I want to focus more in that day and play in whichever I decide. I think it's been worth it. It was nice giving people villagers and it's been nice having another town to sell fruit in, sell turnips, take katie, or get signatures. I couldn't imagine having more than two towns though honestly....especially not more than two developed towns...but to each their own.
i have 5. eyeing a sixth for no real reason.
i got them for dreamies, and the fifth was also for a theme. i quit 3 of 5 copies so i could focus on arkham for now. will rotate them in and out accordingly
i have one but i plan to buy a second as soon as i can afford it, so i can have more dreamies and actually plan out my town more since i didn't really know what i was doing with my first town and i'm too far in to justify resetting it.
