I know the Dreamcast game Skies of Arcadia and its soundtrack by Yutaka Minobe and Tatsuyuki Maeda have their share of fans. The soundtrack will be getting new CD and vinyl editions by Wayo Records, slated for release this summer. The CD edition includes 67 OST tracks on two discs, the vinyl edition 30 OST tracks on two discs. Both editions include a third disc with two new piano arrangements totaling 22 minutes in length.
Details and pre-order links (as well as a limited edition music box for really hardcore collectors) are at the Wayo's album site:
