@Black Terror. Wow, that was a sharp change from your first comment. All of the Medium Crates are a bit more detailed than a box (12 polys), they are 108 polys. Even most of the ones included in FPSCreator are more than 12 polys. Texturing takes most of the work, so calling them "only boxes with textures" is kind of a slap in the face. Not to mention the time it takes to make them FPSC-ready (things like scaling to the proper size, making sure properties are correct, etc.), and put them in an installer that requires zero work on your part (aside from pushing the install buttons).
So I'm going to have to disagree with your assertion. But thanks for taking the time to comment
