I just found this thread after your win. A few comments from a noble player:
1) I vote for one thread please. That is my vote.
2) After a while, as your skill improves, you'll get to the point where you so overpower the AI civs that any benefits from UUs or traits will be superfluous. Sure you are doing a Praetorian rush, but if your advantage is so great that you'd be doing just as well using regular swordsmen or axemen in place of the praetorians, well you're not really showing the advantage of the praets, but instead you are showing how to completely crush the AIs on prince level. At the rate you are learning stuff this should take 2 maybe 3 more games. At that point bumping barbarians to raging as suggested by a previous poster followed by an upgrade to monarch might be in order.
I mention this because my original plan was to win Noble with the 18 Civ World Civ scenario (raging barbarians, quick play, time victory turned off all others on) with each civilization.
After many many false starts, improving my play each game in some way or another, I finally jumped from being barely able to compete to ... well my first win is my current game doing an early chariot rush with Egypt where, now, I have the biggest civ and my 15-2 horsey units are conquering civs defended by 6-1 archer units. OK I have not gotten the complete win yet but now its just grinding out the turns and victory.
The point is: it took me forever and a day to get to the point where I was able to put all of the pieces I've learned from the boards here as well as many many botched attempts. But now that I have the pieces all together, the thought of running through this EIGHTEEN TIMES is somehow NOT appealing.
However, moving up from noble to the next level after I do 3 or 4 more noble victories (assuming they are CRUSHING victories) ... well THAT sounds pretty good
You don't sound quite ready to move up to Monarch yet - or even raging barbarians on your current level - but you'll know it when it is time to move up.
And oh yeah its ok if you move up too soon and lose once or twice

You can either replay that leader or just move on depending upon whatever makes your boat float.
3) I found this thread after your victory was already finished. GREAT job. I found it both entertaining and informative, and with luck will find your next thread while the game is still in progress.
4) What does ALC stand for?
