RAYGAN  I have been using this program for quite a while and I don't know if I could even begin to GM GURPS without it. This program isn't perfect but it's the best of it's kind on any platform as far as I am aware. It makes character creation, probably the most complicated part of the GURPS system, fast, fun, and easy to understand. I waited on switching to 4th edition rules for nearly a year until this program was made ready for them, and now that the update is here I can say that it's really quite good. If you play GURPS, don't miss this program.

RICHARD WILKES  Mac OS X Users - NOTE: The current Java 5 package that Apple is offering for download to non-developers has some bugs in it related to displaying certain types of graphics. This results in swapping of the red and blue channels in the image, giving very odd colored images. In addition, this release also seems to have problems with transparency, so some graphics overlap where they shouldn't. All of these problems have been fixed in the version Apple makes available to developers - however, I don't know when they plan on releasing that version... soon, with any luck. In the meantime, the product functions fine, but may look a bit odd (especially the splash screen).

BC_PETERY  Works like the previous versions, drag & drop Advantages, Disads, Skills, Spells etc.

I miss the Weapons list, tho.
