To be clear, are you saying that I could, if I did want to make my own tiles, use the 'extra' tiles I had (if I got WoF) to make my own? That makes sense, if so. I guess it's just as easy to stick a label onto an existing tile as it is to stick it on a blank one (or however you make them).
You got it. Here is what I did. I played for the first couple times with a set that belonged to my sister-in-law. When I saw the game at the FLGS, I noticed that there were expansions available. I hadn't seen them before and had no idea that they existed. It made total sense to me though realizing that all it took was a few tiles to bring something new to the game. I started researching expansions and got hooked fast. I bought the base game (with River 1), P&D, K&S, and Count from the FLGS. Shortly after, I got the GQ11 and the Big Box 2. My rationalization was that I'd give the duplicate stuff to my nephew and save money on the Big Box. I filled in the rest of the pieces here and there (all I have left at this point is the Crop Circles).
Somewhere in there I found CC and got very interested in the fan-made stuff and decided to keep my base set to make tiles. They are perfect to do so. I bought my nephew a new base set for Christmas and threw in my extra P&D and Count.
This is definitely the long version of the story, but I always suggest that people who start with the base set and look to expand should buy the Big Box simply for the savings and they can gift the base set or use it for customs. I used the tiles from my extra base set and have made about 40 fan-mades at this point.
