Science Fantasy Sandbox. Somewhat a mix of EVE and Warhammer 4000, with on-the-planet content. (Has EvE gotten around to implementing something like that? I heard rumors about it years ago.)

X-Com online, with permadeath. Each player controls one base on earth, or may control an idividual soldier.  Players must cooridinate to make sure that PC soldiers don't get themselves killed, and to help out other bases on the server. You could even do the same thing with the Aliens.

A huge sci-fi mmo, mechanics similar to swg in it's pre-cu form, but with several differences too.

-- the variety of "professions" with the ability to mix and match (combat and non combat professions)

-- player cities in-world, not instanced, along with server cities, built in benefits to both areas to draw players to player cities but also give veteran players a reason to hang out in server cities meeting new people; player cities would not be able to be destroyed but might have some buildings that could (forts), player cities might be able to be "taken over" (not that the new group would gain control of the individual buildings but their faction might have npcs walking the streets and the city might take on certain characteristics of what that faction's "beliefs" are, and there would be a way for the city to regain control...for example a faction that is heavy into industry takes over a faction that is more environmental friendly, the quality and types of resources in the city might change)

-- whoever "founded" a player city would determine the layout/grid of the city, designating what types of buildings/structures could be built in certain areas and who was allowed to place items, and what faction alignments the city had (belonged, friendly, neutral, hostile, etc.)

-- both land and space activity, multiple planets with new planets being added as the game went along...each planet might have different terrains with species that reflected that environment; planets would also be in various stages of development (technology/industry) and awareness of others existence including at least one planet in which there were be an outpost accessible to all but "cloaking" would need to take place beyond that outpost (think Men in Black, aliens are on earth but only the MiB are aware of their existence)

-- multiple factions, with each planet having their own factions/government/conflicts; as the game progressed one or more groups might try to move their faction control beyond their planet to rule over multiple or all planets

-- different servers would have different rule-sets and characters could not be able to transfer between the servers (ranging from no form of PvP to totally open PvP)

Or if anyone remembers the old game interstate 76

Don't know why someone hasn't tried a mmo with a strong driving element, I guess because you move faster the world has to he bigger or something.

Actually they did try, google up Auto Assault.... they sure tried and failed miserably!

An MMORPG in which every one come and complain about how bad modern MMORPG's are blame WoW and cry about SWG...

Bare with me as this is just off the top of my head... 

But I'd like to see a sandbox CCG MMO. More of a virtual world with player housing and a focus on collecting cards and social clothing and social status symbols. PvE should exist and it should be the main way to obtain cards. Crafting should exist and should allow for player housing as well as functional and decorative furniture, Crafting of some card types, social clothing, etc. 

PvP would be card duels and tournaments, you could even have 5 man teams like they do in chess. 

There should be large official tournaments held by staff that offers greater rewards than most things but it should take a good bit to recieve an invite or to obtain tournament tickets to enter these. One way would be to give points to a player for beating higher ranked players, the higher the rank of the defeated player the more points. It should cost a significant amount of points to enter so it is either win or lose and you must wait a long time to enter again. 

I like the idea of titles as well. 

Just a rough idea off the top of my head, may flesh it out more later. 

• A combat oriented spaceship MMO
• Stone age survival MMO
• Age of Sail MMO (just better than what we have now)
• The above mentioned Road Warrior MMO (Interstate '76, Mad Max, Auto Assault, Bandits; Phoenix rising...)
• Wild West MMO

But in all honesty, any MMO made well will do.

An actuall mmo featuring Swords and "Dragons" (crest animal)
no ninja stealth, no steampunk shorties, no magic, no teleportation technology, no levitation.
An actual medieval mmo without the usual hyperbole.

Oh and you get to fight other lords and kings, europe is a pretty explosive place even without monster dragons and dire rats, orks, space-goats :)

Other than that, space shooter style featuring mechs, capital ships, armor suits and ion beams :)

I would never do such a thing.  If I was ever lucky enough to create an MMO it would most definetly be a high fantasy, elves/dwarves/orcs sort of game.  It is by far the most suited for and most fun for me style in the genre.

With that being said, my second MMO would be a post-apocalyptic MMO, set a millenia after the event that almost wiped out the Human race but one in which magic replaces technology. so i na sense it would be very Shadowrun'ish, minus the corporations in control but instead with the Churches of elemental magic in competition.  Think Fire, Water, Earth and Air as the player factions.

My 3rd MMO built would be a Midevil Sword/Bow non magic Survival game in the spirit of DayZ but the Undead as the antagonists, things like Shambling horrors, Liches, Skeleton Knights, and Mind Flayers as the baddies.

if done right i have always thought that The Saga Of The Exiles IP would make a fantastic MMO. The books even have 3 main factions in it that players could choose from

http://en.wikipedia.org/wiki/Saga_of_Pliocene_Exile

Plain and simple.

Dune

My Faction would be with the Freemen http://dune.wikia.com/wiki/Fremen

Farscape Online.

Ah, one can hope.

We live with the knowledge that a lot of suspension of disbelief is required to enjoy a fantasy game.

But Prison? Really?

Can you imagine how many Big Gulps of Unreality you must swallow whole to make Prison fun in any way?

"No swords,dragons,magic,shields or wizards."

Hmmmmm....looks more like these forums here. They are usually quite massive and online. Also they have a huge amount of PvP (poster versus poster).
