When I started playing I just took the first thing that was offered as I was so excited. I wish I knew about being able to choose the town layout and how my character would look like. Now that I have played for awhile I am ok with everything but I am sure I would have chosen something completely different if I had known beforehand. Creating town projects and paths really do make a town unique. I have visited other towns like mine and if I didn't look at the map I never would have realized they were the same. I love how we can visit others through dreaming, it's a wonderful feature.
I'm pretty sure I've got 2C (first box). It's got the narrow bit in the top left and a little bump in the river I've placed my caf? by.
I hope other 2C'ers will post here. I'd be interested in seeing what others have done with theirs.
My layout is the bottom right grid, A2 square. But I haven't finished my town yet so I'll update this with my dream code when I've laid out my paths :3
Thanks for all the replies so far guys! Hopefully we can build a big thread full of DC's and layouts so users can easily find examples of their own towns
I used to have 4-A-4 with the dream address 7900-2406-3038 which was possibly the worst map I could ever have chosen for myself. I then placed large, non demolish-able PWPs in the middle of large open spaces, so I had no space at all for PWPs =/ So yeah, I hated it lol. But the dream address still works so you can check it out.
Still working on my new town so I'll give an updated DC shortly
Mine is I *think* C4 in the 5th box (bottom middle). DC in signature! Probably need to get that updated soon, but I haven't had any PWP requests since the last update a few weeks back
My dream address is in my sig below.
