I bought a second copy about 3 months ago, mainly because my first town has pretty much accomplished everything. I have to say, it has refreshed the fun of playing, for me. I am going for the Fairytale theme this time, Stonac is zen. Also, I've dated Fantasia to a different season (I'm in summer), so I can try to catch scorpions and tarantulas before the town gets too crowded. I have so much open space, it's fun to run around. I'm more relaxed about what townies I get, as well as when the upgrades happen, just letting the game do its thing. I feel less pressure, since I have already experienced everything that is supposed to happen.
I'm Sure you can find a copy for less than $40 these days. Check online.
