Featuring the tagline, "Evil is Good," Dungeon Keeper (1997) distinguished itself by letting you play as a humorously diabolical dungeon lord trying to lure and kill various heroes. Loyal minions will tunnel through dirt to create rooms for your lair, allowing you to attract certain monster types needed to populate your underground realm. If your fiercely independent creatures slack off, give them a swift but firm slap to keep them focused. A sequel was released in 1999.
