Net de Bomberman - Installs to the HDD and requires the HDD to play. Also requires PSBBN 0.30 or higher and a feega account to play. The game boots from the disc but runs from the HDD after that. There's a monthly fee of about 525 yen to play.
Pop'n Taisen Puzzle-dama Online - Fully installs to the HDD and runs from it without the disc. It is the only game to run from the HDD without a disc and to not require a registration code to play, making it the only game that is easy to pirate just by passing a disc around between people with HDDs.
Front Mission Online - Requires the HDD and PlayOnline Viewer. Runs completely from the HDD after installation. Currently in beta testing in Japan.
King of Collisseum (Red and Green versions) - Installation to the HDD enables access to content from both versions of the game at once. I think I also heard it can save directly to the HDD...
Hmm... I think I'm still forgetting something...
