AC2.

Half of it is the fact that I had no idea it was getting shut down until after the fact.  I wasn't yet browsing MMO sites looking for the latest news.

Come to find out, I guess all accounts were activated for the final month and much fun was had(?).  I guess what sucks the most is that I missed out on being able to play it for a while again before it left forever.

Granted, I was stepping out on it at the time (playing another game), so it serves me right.  But to be honest, even though I have had my share of major MMO disappointments, that's the only incident in  the MMO world that actually makes my heart ache.  =)  I truly loved that game, and I kick myself today for not sticking with it until the end instead of whatever PoS game I was playing at the time.

The short answer is Ya!!!!  I am in your boat OP, Aion was a total letdown...

SWG

Warhammer for me... just so sad

SWG... well not the MMO that broke my heart it was more like SoE taking it and then throwing it in a blender and putting in on puree 

Gods & Heroes: Rome Rising. I got to beta test it for a few weeks before it was cancelled and DAMN was it awesome. Heatwave is supposedly bringing it back, but they've literally posted NO updates since they announced that they acquired it. It's definitely a game that deserves a chance, and one that I think could be very successful. 

Middle Earth Online is seriously the most disapointing thing ever. A sandbox game set in the grandfather of all fantasy worlds, and all it became was a WoW clone at the last minute. It was the NGE without the publicity. 

Vanguard is another sob story. 

For an MMO to break your heart, you have to love it first. So many ones that came out and didn't live up to expectations but they never actually broke my heart.

The game that broke my heart was Dark Age of Camelot.

I loved this game and was perfectly happy with it until Trials of Atlantis came out. Taking away the endgame of pure RvR and making you do more PvE to get realm abilities just sank it like a stone. People grew greedy and realm pride vanished. Gone were the days where people would suicide in dungeons to get out and defend the frontiers.  As the populations tumbled, every thing fell to pieces and gone was the game I loved as much as my first MMO, EQ.

Forgot to add STO, perhaps the biggest dissapointment of them all.

Warhammer Online from Climax for never being released and being replaced by WAR from Mythic which totally bastardized the IP.

Horizons: empires of Istaria.

It was a game I left everquest 1 for, and before world of warcraft came out. It was supposed to be a game where players could build houses, towns, all weapons and armor and even talior make spells. It was the first game I know of, that had flying. No content was added for a rediculous amount of time. When an update finally did come, it took away many of the things everyone had worked for. It was a game abandoned by its developers at release.

no game broke my heart bcus i dont get high expectations for a game. and come on, everyone knows that the majority of the responses will be swg. ive been reading crying fanbois for years over that crap.

EVE Online, beacuse I absolutely love the game but don't have enough time to support what I want to do in the game. It really sucked to have to stop playing simply because the amount of time investment couldn't be followed by me, the player.

PvP was sooooooooo fun in EVE... makes me want to play again, but I know it'll just suck to have to stop when work time comes.

Horizons destroyed my innonces and optimisim as a child.

Trials of Ascension finished me off.

Now I'm a bitter husk of a man.
