I'm thinking of deleting my town mainly because I started time travelling. I look at it now and don't think it's worth it for what it would've been. The only reason I started is because it isn't Pick-Up-And play like WW, where you could play it at any time and not miss events. Where-as on City Folk you've got holidays and I can't access my Wii at all times.
I might have to start over though, don't know yet. I could go back in time and just create a new character and use them, it wouldn't feel right though. (wouldn't some of the stuff be sold also?)
Anyways, if you don't find anything fun to do, time travel your heart out. Other than that, try fishing or something. I'm doing that now and it's actually more fun than I'd thought it'd be.
