OVERVIEW OF HOW I THINK A CTF MAP COULD WORK:
There will be two sides available once a player joins a CTF server - red and blue. Once a side has been chosen, each new member of the team will then spawn around a flag of their team's color; spawning on opposite sides of a gameplay-area bordered by four adminium walls and split into two equal halves with a wall made of osidian reaching from the sky to the bedrock layer. The osidian will be mine-able, but only with diamond picks.
As so:

The two teams will not be able to see each other through the border, nor will they be able to see the other team's chatlog.
GAMEPLAY MECHANICS:
The objective of each round will be to infiltrate the opponent's base and return to your own with their flag in hand. (Or invent.) Once there are equal members on both sides, then the round will begin. Players will be given a specified period of time (e.g. perhaps 9 in-game days for short games and two real-world weeks for long games) to gather resources and gear themselves up for the upcoming match; and a date for the battle will be announced.
This will be the time following which the mid-sectional border will dissolve into nothingness, and the two sides will be able to see what one another have been up to ever since the beginning of the game. They will then have a couple of minutes' time to either decide on tactics or take out their battle-gear.
THE FLAG:
The flag will be a colored wool block not movable by either team until the actual day of the match.* On the day, it will be the Blue team's job to take the red team's red wool block and place it ON TOP OF their own blue wool block in order to score. Like in most CTF games,
*Red/blue colored wool blocks will not be able to be crafted in the game in order to avoid confusion.
IN-GAME STORE:
Possibly, a store feature may be added in-game to even out the inequalities in mineral-spread caused by randomly generated terrain. I was thinking maybe this could be done through exchanging an in-game server-side tracked 'score' left over from previous games (Like in Jacob's CTF Server. Cough.) and gained or lost through completing a series of actions, e.g. For Killing a Monster(This makes killing monsters still worthwhile even during the later stages of the game.) killing other players, scoring a flag, returning a flag.
Players could also be ranked in this way; through the total amount of points that they have attained ever since first playing on the server.
POSSIBLE TACTICS:
War-machines such as TNT cannons may be used to quickly take down thick walls. Ability to do so will depend on the amount of gunpowder from Creepers that the attackers have amassed during the resource-gathering period.
Phwoar, t'was a long post. I'm totally out of finger-oomph now.
Would be totally marvelous if you guys gave me a bit of feedback as to how this thing can be improved. There are a few issues that I have on mind at the moment, to do with dysymmetrical maps and upsetting base-defences that I would really appreciate having some thoughts on as soon as I put them down on paper.
It'd totally be a dream come true if this was actually made.
