There was a psychology to DAOC classic that I haven't seen in any game since, and I've played all the major MMOs extensively. You fought for your life because it mattered if you died. You fought for realm because your relics mattered. People would actually drop what they were doing for a CTA (call to arms) to defend their relics because they genuinely cared. You got this eerie foreboding feeling just trekking the narrow corridor into your own frontier knowing it was laced with assassins but getting out to the frontier HAD to be accomplished because it had to be defended at all costs. It was masterful on how it played out... bad graphics, cheats, boring pve all considered.
I'd pay any subscription for a game to make me feel like that one did again and I pity the folks that missed it.
That said, I don't know if that was all an accident or genius. If Matt Friror can duplicate that psychology with this larger MMO audience, the game will be a success. And the arguments being made now over success or failure will never be an issue.
If the product is that good, players will flock to it.
