With the addition of XML feature, some of you may want to make your own XML files as the capsules for your game data, especially with RPGs and turn based games.
Here is a nifty XML editor that will keep things simple for you if you're using XML as a data format: SymbolClick (scroll down to version 1.1, that version is free).
Basically it allows you to edit XML files like an excel spreadsheet, so you don't have to deal with XML in raw text format.
