I did it is listed as Indiana Jones IV i did not even bother naming the pathetic title.

I know the Indiana Jones films really don't have episode numbers like Star Wars. It was called Indy IV in pre production just Like Last Crusade was called Indiana Jones III before release and Temple was known as Raiders II before it got a title.

Clone Wars 2008 theatrical is also on my list as well.

There are no Thx 1138 2, Howard the Duck 2, Radioland Murders 2, Tucker the man and his dream part 2, or willow 2 or they would probably be on the list as well as more american graffiti.

I guess you could add the Land Before time sequels since Lucas had a uncredited role in them as well as the first film.
