Jancsika, sure, a Map Creation page(s) sounds great... I personally like figuring out how a game works, so I can optimize my play. The Menu reflects that. But there is much more to this game, of course...
The Menu I slapped up there is
only something to get us started. I expect and hope for it to change greatly over time. The
X-COM wiki has re-invented itself several times over the years, with major re-organizations and facelifts as it grew from piecemeal articles, to a comprehensive summary of everything in the game. (With a nice looking Main page!)
Also, I'm not the type to make things look pretty... it's just the facts, with me.

But it takes all types to make a wiki, so anyone jump in with whatever they want to do. If you are considering doing a big change, ask about it first on the Discussion tab of the Main page.
I've already learned something, as of the second page on Interface, posted by Initsol... now I see why Maintenance uses that odd 5.2 year period. It's 1,000 of the 16 ticks per month! Interesting page, thanks for that.
Which reminds me... "Interface" might not be the perfect place for that. (I was thinking, Hotkeys, etc. when I slapped it up there.) Everyone feel free to make a new entry or tweak an unused one. That menu is only a straw man. Modding is so big it should have its own top-level Menu entry on the Main page... somebody please add it.
Falconer, it's looking great! I know others have tussled with the naming problem...
Oblivion also made the same choice. But if there's any way around it, it sure is nice to be able to just have to put a topic in [[brackets]] and keep moving. If there isn't any practical way, though, c'est la vie.
