Though possibly the most popular, the world of MMOs spans far beyond the realms of Everquest and World of Warcraft. There are hundreds to thousands of well-developed and even free online games for you and all of your friends to enjoy. You've just got to know where to look.

It could take forever to go through each individual website of every MMO you may be interested in to check out screenshots and gameplay. However, I'm here to share five MMO directories that I've had plenty of luck with in narrowing doing the choices.

These directories do all the work for you and present the most enjoyable, sustainable, and free games to the user. All you've got to do is make the decision on which to play or download.

Free MMORPG List

Despite the name, Free MMORPG List features much more than just massively-multiplayer online roleplaying games. It's first on the list because it's probably my favorite. The site features categories for free, action, strategy (or RTS), kids, simulation, sports, browser-based, and social games. The site features 28 pages of games in total with a dozen of games displayed per page. The listing of each game offers a high-quality description, screenshot, and immediate links to download and visit the game's official website.

What MMORPG

If you're specifically searching for a MMORPG, What MMORPG is the absolute best resource you're going to find online. What MMORPG takes this MMO genre and breaks it down into subgenres of fantasy, horror, modern, space, superhero, historical, racing, and so many more.

You can also narrow games down to their cost (free included), their play style (PvE vs. PvP), their developer, and their artistic style (2D, 3D, etc.). This is a very extensive resource. Game listing pages also include ratings of every game, contributed by players like yourself.

F2P Games

F2P Games is 100% dedicated to bringing you MMOs that are completely free. This directory also separates free browser-based games. F2P Games also includes a very interactive and informative forum where you can go to get all the latest user-contributed F2P news.

This directory contains a little over 100 games for you to choose from. It's got a simple list style: not as descriptive as the rest in this list, but you can browse and choose what you want quickly.

MMO Games.com [No Longer Available]

This directory has the benefit of having one of the better eye-pleasing designs compared to the rest. Not much sets MMO Games.com apart from the rest, but they do have specific categories for mobile and Facebook games.

The site features MMOs in general with a slight bias towards the MMORPG genre.

TIGdb

The Indie Game Database is a lot different from the previous directories we've mentioned. This website currently features 757 games, all created by indie developers. Not all of them are free and not all of them are MMO. You will be able to narrow down your selection using their filters though.

This directory is really cool and unique and a refreshing change from the rest. I managed to find one of my favorite indie games ever, Altitude, using this very website.

We've wrote before on MMO Hut, a similar directory. We've also whipped up a nice little article showing you three of the very best MMOs to try out. Got any more suggestions on where we can go to find these games, or fun and free MMOs in specific? Share them with us in the comments!
