A MMORPG version of this game would be awesome. But that would:
1) force monthly pay
2) force armagen to get more employees (does he want this?)
So a server that can be hosted by a player would work out better, just as with counterstrike and such online games. The no-monthly-pay would also attract more people.
Also, hackers/cheaters on player-hosted-servers would be better controlable then on a mmorpg server. It's terrible if a mmorpg server has hackers/cheaters running loose. It would damage the reputation of the game a lot.
So I would gladly see a multiplayer version of this game, but don't expect it to ever become mmorpg unless it's going to be a whole new project with more employees perhaps. Or perhaps a whole other game developer "stealing" the concept of the game.
The singleplayer version of this game isn't finished yet, so let armagen first concentrate on that. If all seems finished he might still make "Mount&Blade Online" as his next project

And how is the forum going to know that you were the guest? Anyone could have posted that message, so that's why you can't edit it.
