Easily,

Borderlands MMO

This game would be beyond amazing in an mmorpg format. It would be something new and fresh that would make Firefall and Planetside 2 look pathetic.

XCOM

Prefer fantasy, but I think that this has a great potential.

Problem, I have with this (while it is a good idea) is that Elder Scrolls focuses on you being the sole hero of the game. And this is the problem I have with TESO. It really doesn't make sense. It's like "You are the dragonborn", "You were chosen by Septim".. etc. It doesn't really make sense if everyone is running around being the dragonborn.

But the actual gameplay, mechanics and world would be an amazing place. I love the progression system from Skyrim in how you choose the skills you want from many trees. I think more games will be doing this.

Do we even have a god game mmo - we need one.

this here , skyrim with mods for realism and housing is by far one of the most emersive games on the market today , but a lot of that comes from the dedicated mod community and not the actual game designers.

I cannot even play vanilla skyrim anymore i gotta have thirst hunger sleep mods and hypothermia and the new and improved perk systems . What an awesome game , I really wish mmorpgs would do this stuff also and make it fun in the process.

When I encountered this wish, I was playing Oblivion.

Can i do the reverse?

I wish tor is not a mmo but an online game with better more actiony combat.

Mass Effect

W40k not done like the failure that WAR turned out to be.

- Mass Effect (in a different timeline from the Single Player trilogy)

- Starcraft

- Full fledged mmorpg of Hellgate London

- Neo Steam (it was a failed korean mmo that shutdown. I would love to see a good developer work with Atlus and re develop it from scratch. More steampunk and less fantasy)

EDIT: i almost forgot... Project Copernicus! D:

Thief: The Dark Project/The Metal Age

Such a rich world, it would be a fantastic setting for an MMORPG.

Thief

Half Life

EDIT: These are tabletop games, but I'd love to see an Strombringer/Elric MMO.  Also RuneQuest and the Morrow Project.  And Traveller.
