VIII, properly patched, would be a fine addition to the site. The game really wasn't all that bad, and only got its "Super Avatar Bros." nickname because of a badly thought-out game mechanic that was done away with in later revisions and patches. I see no reason why it shouldn't be here, honestly.
As for IX... I don't know. IX has a really nasty reputation among Ultima fans, for several very good reasons. Even after its last official patch, the game is buggy, poorly designed, entirely too short, and ignores the events of previous games in the name of plot convenience. It should probably be here for the sake of completion, but it would need at least the fan patch (which rewrites the script to take earlier Ultimas into account, among many other things) to be considered at all "acceptable" by series devotees. There's precedent for this; Might & Magic IX, which has a similarly bad name in that fanbase, is sold with a fanmade patch in place.
