I'm not really a DnD player, but it didn't feel so alien to me.
There are more similarities to the original series than I think people might realize.
Of course, I also played the OG unpatched BG1 CD and I doubt anything could feel as terrible as that.
People just may have a hard-time coming to grips that there's a sizeable luck factor with the DnD system the games are based off of. Anyone who's unfamiliar won't consider options they have to offset that.
