There are too many names to name individually, so...
To Regression players: I love each and every one of you (even Dezreki). Regression had the finest, drama-free gaming community I have ever had the pleasure of being a part of. All of you made MxO the experience that I'll always remember. The Trust, Prophets of the Martyr, Prophets of Peace, The Royal Guard, The Revenant, Chambers of Shaolin, the Devil's Advocates, and any other Regression faction that time and old age have faded from my memory made the Matrix for me. I learned so much about the game, the lore, and meanings in the movies from all of you.
The Trust: When we first formed over four years ago, someone told me "You'll never get anywhere if you're not a beta faction in this game". How very wrong they were. The Trust was comprised mostly of non-beta folks like me... lo' and behold, four years later, we end this game as one of the top Zion RP factions; not just on Recursion, but in the game. Each and every one of you have contributed so much to this community and to the dedication in giving people stories to be a part of... you all should be proud. Not in my wildest dreams would I have thought that I'd meet such an amazing group of people in a videogame. Some I've met, most I haven't... but I'm proud to call you guys family. <3
The Mega City Department of Energy: My home away from home away from home. I still keep my badge shiny. Yet another awesome group of people that I'm proud to know. There's a lot of bad rep towards the DOE that isn't really deserved... the goal has always been to bring to light the truth, something that many members of this community did not want to get out. If you look back now on everything they have said and done, you can't deny the truth, or the spirit of goodwill and fairplay that they advocated. The DOE has never given a crap what anyone else has thought, and they've always spoken our minds. It's an honor being a member of such a bizarre mix of people that somehow get along (most of the times). And yes, the DOE won the game.
Special mentions:
Bindi: Don't know why I'm typing something here since we talk and game together everyday. I think everything I need to say can be summed up like this: <3.
EndlessVoid: I'm glad to have you as a friend OOC, and a rival IC. You're one of the best RPers and community members this game has ever seen. Much of my own RP was inspired by you, and Void has always played a huge role in Fenshire's life. Thank you for the opportunity you opened up for me, and vouching for me. I'm sorry if it happened to come at a time where I wasn't as active on these forums as I had been. 
KnifeEdge: One of the first people I met in the game, and I'm glad to see you back for the end. I'm sorry for the suddeness of me leaving the Trust and dumping a lot on you back then... but you did an amazing job with it. I'm glad to see us both in game with the same tag over our heads again. I hope you can understand my reasons for leaving back then. I needed a change.
Th3ra: Like Void, you played a very important part in the building of Fenshire's character, and an important part of my life. You helped me through a very difficult time in my life, and I'll always appreciate you for that. We don't talk as much as we used to, but you're one of the most amazing people I think I've ever met. There's still room for you on the Devildog!
TIMMCAM, Merrit, Reposco, and Zeissman: Without a doubt, hands down my favorite liaisons.
Vogt: Thank you for the hovercraft battles. Towards the end of the game, it was the only thing left that I truly enjoyed doing. You're a brilliant dude. And special thanks to Neoteny for keeping them going.
Ebola: You'll be the first to whine that I didn't include you, so here you go.
Seriously, though, I loved having you as the target of all of Fenshire's Cypherite enmity. Like Void, you made an awesome rival. Can I write the story where I kill you now?
Sieges: I know things I've said have bothered you, in reference to your RP and all. I'm sorry if I ever hurt any of your feelings... it really wasn't my intention. I think you're an awesome RPer, and a great friend. You've always been so nice and sweet to me in game (more than I probably really deserve). Hopefully, we can still keep in touch.
Raijinn: You ended up being cool in the end. As MxO shuts down, you're pretty much the only SOE employee that I still have some respect for. Keep it real, dawg.
That's all I can think of for now... it's 2:45am and I'm getting a litty misty writing this. Dang, it's so hard to say goodbye to this game. I've met so many people and had so many experiences that it really had become a big part of my life. Despite all our flaming and trolling of each other, this was still an awesome community.
I'll let Boyz II Men close this out for me:
