If you want to try something which comes really close to being a real Baldur's Gate MMORPG, then you should definitely try BGTSCC based on Neverwinter Nights 2. It has the feel of the old single player Baldur's Gate but it also has all the traditional elements of MMORPG games. It is actually more of an MMORPG than DDO because in DDO people can only have 6-12 player groups, whereas in BGTSCC there have been big events involving groups of 18-30 player characters on the same maps.
In my opinion, BGTSCC is currently by far the best Dungeons & Dragons MMORPG experience outside PnP and it is certainly in an absolutely different league compared with DDO or the new Neverwinter MMO.
