What would you want in an MMO

Me and a few friends have always wanted to make an MMO Recently we've been getting more serious about the idea, trying to figure out the Story and all that stuff. But I was wondering what would you like to see in an MMO and what are your favorite things in MMO's?

-I love customization, and maybe some weapon enchanting like Oblivion.
-Different armors available at different levels.
-Different races
-Able to buy land, and build a house, or buy a pre-made house
Those are just off the top of my head, I can think of more later

Hmm, thanks I appreciate it.

You need a nice combat system in an MMO.^^^ what he said aswell^^^. None of this Runescape clicking junk. Not that a RS type of game play is a bad way to start cause that would be great.
All the MMO's these days seem to take from WoW and such games and just expand on it.

One thing I can't stand in WoW Combat-like systems is you can't cast spells while moving or shoot bows or guns, in ours you will be able to, for sure.

If you can cast spells while moving, then mages will be to over powered. Also, in WoW you can shoot bows and guns while moving. You just have to be facing the enemy.
