I have no doubt that it will be a good MMO, but I am sick to death of dev's turning every good RPG into an MMO. Seems like the only one that has converted yet is Bethesda. I highly dislike MMO's for several reasons.
1. The monthly fees. I would rather not game again rather than pay for a game, then pay monthly to play it.
2. They seem to require guilds, friends and factions. I hate having to join up with people that I don't know just to have fun in a game.
3. They never really seem to have an end. Usually they slack off on the story BIG TIME and flood you with thousands of options for creating your ideal character.
4. There are no decent RPG's that are single player. I can count on one hand how many decent RPG's have been out in the last 5 years. Kotor, Oblivion, Fallout 3, Titan Quest and NWN.
Sorry to say it, but The company that had Duke Nukem rights had rights to a Fallout MMO and when they tanked the rights fell into Bethseda's hands, and Bethseda made an MMO department in 2007, my bet is you will be seeing one.
I understand your arguements though, especially with current MMO's. Story is going to start getting better as technology does, it's hard to feel immersed when you have to read a wall of text, most are pretty lowo n character creation options, just lots of gear options. If you played the first 20 or so levels of AoC you would know what I mean, they did an amazing job there and your own character wasn't voiced, which in this they will be, and the whole game will be, I think it's going to be very enjoyable to hear the story.
The monthy fee though isn't too bad, if you really enjoy the game you won't buy a ton else. I buy maybe 5 games a year, I use to buy 10 or more, so it balances out, I just find myself buying exceptional titles rather then picking up mediocre titles to fill my time.
