RBION is a keeper and a great game.
I think the playfield is beautiful. One of the best out there, IMHO. The backglass? I feel like it tried to get the TZ effect but didn't quite make it. Is it ugly? By no means! But it's not a best by any stretch either.
IMHO RBION got "hurt" by RGP back in the day (2004) because a loud but small group of regulars bitched about it. Hey, it's their right to voice the opinion. That, along with the fact that it wasn't distributed in large numbers (I believe) meant that many people just assumed it was bad but didn't play it. Also, in general, I believe there was a lot of Stern hate back then. Not so much now! Over time it's starting to show its real value.
Just my opinion.
