Feel free to add any if you want, or get together a group to put it together. I've just been working the MTW stuff, trying to get it organized around a decent main page for the game. Not too many people play the game still, and not too many of those seem to be aware of the wiki yet, so I've been pretty much winging it on my own (which means there are lots of errors in the game mechanics pages, I'm sure).

The MTW templates for units/buildings/provinces aren't really compatible with RTW or M2 due to different stats and game mechanics, but they might serve as a starting point. I can make some page templates for those games if you want, but I'm not really sure what would be good to show, so I would need some guidance. I haven't played Rome since 2005, and never really got to the point where I just had to know the actual math behind the game.

For the MTW wiki, I started out by looking through guides and game files, figuring out what important info I thought should be added to the infoboxes before actually coding them up. For units, think about melee, missile, and mounted units as a whole, non-applicable stats can be hidden in the pages. Unit, building, and province pages are fairly easy once the templates are in place, just tedious due to the large number of entries and stat verification. The game mechanics pages are tougher to put together, mainly because I have to dig through threads to get details I have forgotten or were ignorant about in the first place.

It's also important to have a consistent page naming convention, to avoid topic duplication and to make linking easier. The advantage of a wiki over a guide is the quick navigation between pages, making the relationships between topics clear and concise, so the internal links must be easy to add. The one advantage I've had doing the MTW wiki is that I have been able to make all these editorial decisions myself, so I haven't had to coordinate page creation/content/naming with anyone. If a group (or just random members) start doing the RTW/M2 wikis from scratch, someone needs to lay down the ground rules and coordinate all of that, or it will become a jumbled mess. After the main content pages are in place, this coordination won't be as important.
