Don't forget that the multiplayer capability was something that was intended for Dragon Age from the begining but a marketing decision removed it because it wouldn't generate enough gold coins.
Incidentally, you know this .... how?
As far as I know, MP was something they decided never to work on originally, not something that was originally there but got "feature cut" out of the game.
BTW, I don't know what "broad audience" you're addressing. I was playing single player RPGs before there was a BG1 or BG2, and I have fond memories of those. Hell I played the original Bard's Tale, not the sequel. I don't know how narrow a gaming community we were back then, but I was part of it.
There was a time where you could, as a single player, run a party of characters. Yes, I know,
that's not how you do it in Pen and Paper where you just play your own, but that difference was established early on for CRPGs. For a while I thought that type of CRPG was disappearing, being replaced by only games where you either play a single char and ... that's it (like Witcher or Oblivion), or you play a single char in a world full of dozens or thousands of other people playing their char, mostly asking you to buy their gold, duel them, or check out their raiding gear.
Thank heaven it feels like the "classic" era is back - but now with today's graphics and engines - and a Toolset for modding. I'm in heaven, or would be, if the recent expansion wasn't plagued with bugs & a rushed feel.
