Neverwinter Nights 1 & 2 have reasonably fun bard classes to play. They are pretty boring in a lot of games though, often sitting there as buff/debuff bots. They're best when they mix musical magic (mostly buffs and debuffs, but other active stuff, some minor healing), rogue-skills, lore, and charisma to make a versatile character. Not too many games quite do that combo though.
