More than 20 years have gone by since Iron Crown Enterprises released their first Middle Earth: Collectible Card Game (MECCG) set. It only lasted a few years, but that doesn't stop some of us from pulling it out as often as we can.
The MECCG designers had a hard time knowing when to stop, though. ("Delved to greedily and too deep" into the complexity of design, one might say.) The addition of dragons, agents (ugh), and then entire new playable factions (Ringwraiths, Fallen Wizards, Balrog) made the game a complex mess that required a huge amount of effort to learn. A basic two-player game could take hours to finish. There are some really cool themes in every MECCG set, but actually playing the game became more and more difficult. Eventually, the game collapsed under the weight of some unsound business decisions from the publisher, but I'm not sure how much longer it could have continued to grow regardless.
There are still World Council web sites. Haven't heard anything for a few years, so that may finally have ended, but I still get the occasional email from someone looking to sell cards or find out info about the game. And you might find MECCG players at several of the larger gaming conventions, often playing small tournaments with the pre-constructed challenge decks.
Locally, there are a few of us who still play whenever the opportunity arises. For years, we'd use sealed product that we'd picked up for practically nothing once the official game support had stopped. It ran out eventually, though. Now we mostly take a whole bunch of cards and randomly divide them out among 3-5 people, then play the results like a sealed deck. These games are generally bloodbaths. Kings of Gondor, Elven Lords, Wizards, Men, Dwarves, Hobbits...the corpses pile up. Even if you play it safe and stay away from dragon country or the heart of Mordor, there's still plenty of danger. Especially since combat involves dice rolls, and those things are treacherous. More than one mighty warrior has been defeated by the dreaded snake eyes.
There aren't a lot of games that I still get excited about playing, nearly 20 years after they went out of print. MECCG may be a complex mess of overly-ambitious design, but it's still one of my favorites.
