Woo. More fodder for the restorationists XD because while it does have some ad-fuxoring, it's not as much as the 2004 version; and it does have cleanup work, though again not as much as the 2004 version.
The 1997 version is the happy medium, imho. I can LIVE with most of the 1997 changes. This includes the 1997 version's ROTJ ending. At least it doesn't have some half-ass hack to put someone else in place of Sebastian Shaw >.<;;;;;
