Just thought I'd give this a little bump. I completed this project a couple of months ago and made about a hundred tiles of different sizes, recreating almost every room from Left 4 Dead 1 and 2. The tiles are meant to be mounted on foamcore and are all in multiples of 3x3 inches but without a grid, although one could be added because most walls go along 1-inch-increments. The 3x3 inches footprint ensures compatibility with World Works Games stuff.
All tiles can of course also be used for any modern or near future game.
If anyone is interested, I will send you the package, but there's one catch: You have to add me on steam so I can verify you own a copy of Left 4 Dead 1 or 2, otherwise I'd be illegally distributing intellectual property (yee above).
So if you are interested, my steam account is "chernoskill"
