Development Size

Uh huh, look at that. That's including the Dreamcast/PC folders (with packed data, combined probably about 80MB) and the rest is the Development folder and minor subfolders in the main directory. Most of the data lies in the DEV folder.

You have no idea how hard it is to get great-looking, hi-res data and be forced to cut it down for Doom simply because nobody in their right mind would download a 400MB Doom WAD(s) {I just guessed there}.
