Definitely Supernova. I mean come on, it turned Jupiter into a friggin' donut yet it couldn't kill three humans.
Also the Fort Condor battles. You could just leave the enemy reach the top and then kill them with your main characters really easilly. But then, it was actually aloada fun taking the time to stop the invasion with your hired troops and defenses.
