This should have gone up weeks ago but I have been lazy. Still am, so all I will give is a quick summary, maybe a link.
I am not a big fan of 4e. In order to get myself interested in just reading the books (to date, I have barely read anything beyond the class descriptions and the 1st and 2nd level powers), I decided to make up L5R characters using the 4e rules. I stripped away all the 4e flavor and inserted the L5R flavor. I got this and more (have not updated the pdf recently either):
I am now working on Avatar the Last Airbender, except that will require a mechanical change rather than just flavor. I want the benders to have unhindered flexibility so they will have X number of encounter power slots and can choose from their list of encounter powers as they go, thus always having the most advantageous bending at any given time. This may be true of utility and daily powers as well. I thought about getting rid of daily powers but then I remembered that they seem to get pretty winded after doing a spectacular bend so there you go.
