Wow, I started to answer this thinking it would be relatively easy. I find myself having a really hard time making a recommendation here.

We just started playing MxO and we are only going to be playing for a month. This is part of an experiment; a trek across the MMOs, if you will.
Welcome. The Matrix has you.

Given that I've only got a month, what do ya'll recomend that I experience? Should I run every mission I find to get into the story, or powerlevel to experience all the options?
Any recommended Archive missions?
If you only have a month, I suggest the following:
- Level to 10 doing contact missions, tagging all the hardlines, and cracking all the neighborhood access nodes.
- After you've hit 10 and chosen the organization you most identify with (you might even consider joining a faction, even if only for a short time), play around with the different loadouts. The best thing about this game is the ability to change 'professions' on the fly.
- Experience the MxO storyline - there are two chapters you should get into, more than any of the others:


- I recommend you go about this in the following order: watch the cinematic first, browse the Sentinels from that time, and then do the corresponding Archive missions. DO NOT WATCH the DotD cinematic until you've finished all of the Hunt for Morpheus chapter.
- Then, spend the rest of your time working on the Pandora's Box quest. In my opinion, it's the best content created for MxO to date.

If you could only get me to see one thing about MxO, what would it be?
Aside from the Combat itself (our Interlock combat system is truly unparalleled in MMO's), I would say the Pandora's Box quest.

I understand that Roleplay is one of the major draws of this game; how does a Non-Roleplayer who hasn't even seen the third movie get into it?
Get into the story. Not having seen the third movie might even serve you better than if you had seen it. Of course, as a fanboy, I strongly recommend watching it.

Whats your opinion of SOE?
From my POV, SOE tends to take a quantity over quality approach to MMO's. Instead of trying to match Blizzard's numbers with just one title, they are taking marketshare on ALL their titles together. This is a good financial strategy, but it sucks from a player's POV because it means that each game suffers; some a little like EQII, and some a lot, like MxO and Vanguard.

What is the best source of information about the game? Is there a wiki?
Well, there is a wiki, but it's not very helpful. I'd point you to these four sites as being the greatest resources for the game:
Omega Syndicate's MxO Fan Site - http://www.thematrix.rumbaar.net/index.php
Othinn's History of MxO - http://archivalscience.shock-therapy.org/
Superjenius' great story resource - http://mxo.mxostory.com
Riac's Outstanding new resource site - http://mxomainframe.com/index.php
I've been working on a player guide, but it's not nearly finished. It does have more links and such, though - http://matrix.hax.nu/mxoguide/guides.html
Other than that, enjoy your stay. You'll be back. No one ever truly leaves this game.
