• Disgaea 2 - can't ever find the time to sink my teeth into it. 
• Okami - just got it
• Rogue Galaxy - wrapped in plastic for 1½ years now
• Shin Megami Tensei: Digital devil saga 1 & 2 - also in plastic
• Fire Emblem: Path of radiance - Where'd I put my Game cube?

..not counting the ones I've played at least 15 minutes.
