The art is shockingly bad. I'm pretty open minded in general with art, but Prem and LE are just awful. It doesn't help that by contrast all of the GnR variants look incredible, and that was the last major comparable game announced.
Add to that the fact that the only art that is reasonably decent-- the Pro-- lacks what seems to be the most interesting feature of the machine in the electric magic toy.
At least for me what they've done is made a combination of artwork and features that make it so there really isn't any of the 3 that I want to buy. If I buy the one with the art I can stomach, I don't get the features I want.
Honestly it's so bad that it just makes me want to buy a GnR more, even though musically speaking I think I'd definitely prefer to play Led Zep.
I understand that it's a tricky business, keeping these things secret until announce, but I think this is a strong indicator that they should really consider offering additional art variants for each trim level if possible. That way if they swing and miss on one people can at least still buy the machine at the trim level they want by picking alternative artwork.
