Not sure how JE looks like or how it plays, but part of the IE games charm was the party based adventuring. And, that you could use terrain in the tactical combat (i.e. move around, use area effect weapons, ranged weapons, melee weapons etc. all at the same time).
Something that I found NWN (and Kotor1&2 for that matter) woefully inept at in singleplayer mode...
While I still have a game of BG2 going, NWN and the Kotors are gone. They might be technological advances, but they just aren't as fun.
Heck, for all it's primitiveness, even Ultima IV is more fun :cool:
