Yeah pretty much this, I took the lazy route and use the mod tools instead of learning to extract the ingame stats
I know it's been a while already, but since the thread just popped up again I thought I'll let you know that I've finally been able to parse the in-game files to get the up-to-date unit stats.
All you need is basically the sga extractor that comes with the mod tools and a tool to convert relics .rgd files into something legible. Luckily leithianz posted the link to a converter recently that works like a charm. If you need more detailed info feel free to let me know.
Anyway, it would be really sweet if you somehow found the time and energy to update your site, since it's arguably the number one source of information out there and so convenient to use.
