Savage Worlds character making software, Wild Card Creator. I'm especially happy for the release as I am beginning a massive Savage Worlds campaign and any time saved managing characters is greatly appreciated.
Wild Card Creator is still not a perfect piece of software, but it's definitely getting there. At this point you are best using the software to run vanilla games or use one of the currently supported settings. If you are going to create a custom setting, which is probably unavoidable for most GMs running Savage Worlds, I highly suggest that you keep your rules changes to a minimum or simply use the vanilla rules and edit the character sheet after export to best fit your setting.
For example, for my cyberpunk setting I wanted to create an Arcane Background for Netrunning (hacking in cyberspace), but for the life of me I could not make the custom AB work. As a solution I am simply using Weird Science, house ruling the differences in the program and then renaming the AB on the character sheet. It's a bit more work than I would like, but programming these ABs are obviously tricky and SW characters aren't that hard to manage on paper anyway.
Another tip: use a custom setting if you are using any Knowledge skills. WCC only supports Knowledge skills that are explicitly mentioned in supported settings, which means that they are impossible in a vanilla game. You will need to create a skill for each Knowledge skill in a custom setting to give a character any skill that's not on the menu. I expect this to be fixed very shortly as it is probably the one feature that is missing regarding running a game only using the core rules.
So, should you get WCC? If you are running a game only using the core rules or one of the supported settings, definitely. It's a real time saver and will have you spitting out characters in minutes. However, you may want to hold off if you are into making custom settings with new Edges, Hindrances, Skills, etc.
