I would like a recommendation for any MMORPGs that you play except I don't feel like paying and I can't require too much out of my computer like 6GB of RAM and things like that.  So if you know of any please tell me.

A free MMORPG, I think I will suggest you Eden Eternal, this game is really good, free downloadable and the registration is free.

Now, in this game, you have the possibility to change your class whenever you want but, at the beginning, you have a few classes and you can unlock the others depending of your level. And yeah, I have to say that the graphics are really good, manga style ^^

I would say get Allods. That is a fun game and it is not all that non computer friendly. I guess that it is the best out there. Besides Runes of Magic.

I'd vote for Eden Eternal or Runescape, if you like grinding.

They're all free and relatively low in size, so you shouldn't have any problems with them.

A good mmorpg is called tibia, it has really bad graphics but is a good game, check it out

I love maple story. But haven't been playing lately because my laptop froze and broken down. Need a gaming laptop .. those are so expensive :/

Another good one is Forsaken Worlds. I used to play it for awhile. Now, I got other things that I have to do.

There are a lot of good mmo games out there and ive played a few of them, some suggestions from me are: Runescape, World of Warcraft, League of Legends, Wakfu (if you can deal with crazy french moderators), minecraft, or Eden Eternal.

well this one isnt exactly an mmo but just a normal RPG with AI. Mount & Blade is a great RPG with AI characters and a somewhat dynamic campaign. when i say dynamic campaign i mean sandbox-ish. it has 3 different games. the best one is "Mount & Blade: Warband". it also has many mods for when you get bored of the normal game. it has multiplayer too but i dont personally enjoy is as much as the single player game.

I would recommend runescape, Adventure quest worlds and maybe Fly For Fun aka Flyff it is a fun MMORPG and is also free. Friend me on runescape if you get an account Mariobros618 is my username same with AQW.

If you have a PS3 you could download DC universe online. The biggest headache with that game is that the server sucks and crashes quite a bit, but the developers have fixed a lot of issues. If you just want a mmo on the computer, you could just go for Star Trek Online. Its improved a lot since it came out a couple years ago, plus the graphics are good for an mmo.

I would have to say Flyff on a private server, Fiesta is also fun and similar in many ways, but is more quest based while flyff is a team/solo-grind. Both have pretty good graphics.

Now a-days I wouldn't recommend Runescape for a 6gb hard drive you have. But if you want to play Runescape, I would recommend doing Runescape Private Servers. The best one I've played so far would have to be one called Fatality614. It is a RSPS spawn server where you can spawn almost all the items you want. It is also 100% free. No download it required, but it's optional. But if you don't find it in your taste you can always go to Runelocus.com/ or top100arena.com/ or rune-server.org/ . These are the only three sites with RSPS's that I would recommend. Any of these sites can take you to thousands of different RSPS's. Also if you don't want to play an RSPS, then I would recommend maybe going on FunOrb.com. They have many minigames/ Full games, no downloads, it's a branch from Jagex, the owners of Runescape, and it's fun and easy to play, along with being able to play with a massive amount of people, also! -VenomSOA.

Since there's a few good ones already I'll simply add a couple more that I play that have yet to be said which is
1) Shin Megami Tensei: Imagine, if you want something different from the traditional level up to get skills etc.
2) Dungeons and Dragons Online, I'm not sure I have to explain this one too much, it's like your good 'ol RPG but different all the same.

Phantasy Star Online 2. You can use bumped.org to learn how to navigate through all the Japanese. The game has a very large English-speaking player base on ship 2. It's a free game, and it only needs 2GB RAM to run it. There's also graphics settings that are very friendly with older computers. 

Try Moon Base, Sherwood, Tanks, these MMO are free and no download. I like these MMO. But the only MMORPG in these is Sherwood.

Honestly, you can check out MMORPG.com and compare like that. Mostly, it hleps to know what kind of games you like, y'know, Sci-Fi, Fantasy, etc.

As for a real recommendation, well.. if you caught me a few months ago, I'd have a whole list for you, but I haven't played any in so long, I really couldn't say. Sorry.

For a good MMORPG these days I would recommend Eden Eternal as well. While I didn't get into it that far, the game has a lot of potential if you can find a good group of people to guild with.

C21 Steel Battle Chronicles from Cyberstep is also a good, robot-based MMORPG but it doesn't have a very large member base and the developers don't seem interested in managing their forum. It is a Pay to Win structure but there are a few ways to get the money currency besides paying for it. It has some fun game mechanics though and if you find the right people you can get ranked up and gain access to the later areas which will have good weapons and parts to use. (Get access to Venev on the Cosmic Renaissance Dimension and purchase Heligal or the Plasma Laser)

You can also take a look at Aion which recently swapped to a free-to-play payment model.
