Haven't found a study of the backgrounds in the Guilty Gear X series anywhere in the 'net, and I think it's one of its highlights. We could talk about their kitschy-but-amazing mix of influences and whatnot but I'm especially interested in their evolution throughout the entire series and which pieces belong to specific entries. So:
GGX pieces (not in all their glory, because they lack the sprites, but still):
The following correspond to the bosses' backgrounds, so, in order to not spoil anything of their awesomeness, I'll just linke them:

I'm asking because I'm starting to play GGXXAC in its Plus edition after skipping XX and Slash, having only played X back when it was released for the DC. The thing is I bought Sharp Reload and Slash for the PS2 and they're still unopened, so I'm thinking of selling them.
Now I didn't like most backgrounds in XXAC much, and I believe there're many of them which were exclusive to XX and even Slash. So the question is which ones? Is there any background from XX absent in Slash? (This is what will make me decide whether if selling them or not.)
Notice I'm asking about brand-new, not counting "revisions". And I'm aware that you can unlock old backgrounds in AC Plus, but I'm not interested in that if you can't see them in Arcade Mode.
What about Isuka? This had brand-new backgrounds but at least one of them is present in AC, isn't it?
Of course, this thread will grow more efficiently with more pictures and/or links, thanks!
