Well it is of course just as well possible to include a database generator in the game itself and let it regenerate (parts of) the database when it detects changed .xml-files. So for the part of making changes and wanting to see the results immediately shouldn't be a real obstacle I think. What I find important to notice as well is that Lua is really a programming/scripting language where-as XML is really a data-container format. So storing data in XML seems more intuitive from that point of view to me. Then when speed comes into play sqlite (or any other database engine) is (to my opinion) by far out the best solution to work on huge sets of data. -- Giel
