GURPS Expanded Grappling
Last year, the largest project on this blog was Expanded ANTOG, where I (with lots of help from Nate) turned ANTOG into a grappling system that can do everything the others can. Before doing all that, I conducted an analysis of what it can and cannot do. However, ANTOG is a somewhat radically different grappling system, and it's not everyone's cup of tea. While I do like it, I also admit that there are some shortcomings to it, especially when it comes to the speed of resolution. So, here's a document that should turn your vanilla grappling system into something much more complete.
