My oldest doesn't only play Aareck the Fighting Man (who has now climbed to the lofty heights of 4th level); she also plays Blade the Reckless (level 2 fighter), Soren the Elf, Sister Kaylyn, Mitchell and Quarren (thieves), and a few others.
Likewise, her sister has about 8 characters of her own, all based out of the northern frontier town of Threshold. This impacts how we play in several ways:
- Players don't get bored with mechanically simple characters; unlike with later editions, the variety is found within the game, across multiple classes, not within the build of a specific character class.
- When there are casualties, replacement characters are readily available and restoring a beloved character can trigger its own quest (e.g. we played Rahasia (B7) as part of a quest to bring a lowly 1st level character back to life). And on the DM side of things, if the characters make a foolish choice, I don't have to hesitate over letting the dice fall where they may.
- As DM, my job is to continually toss out LOTS of adventure leads ... more than the group could ever follow up on ... and let them choose which characters to send on which quest. It enables player agency over simply having them ride the "plot train" of some adventure path that I've predetermined ... which keeps things more exciting for me too.
- Because we are dividing play hours between about 24 characters (including NPCs and the characters of a half-dozen friends who join us sporadically), in groups of about 4 adventurers each, PCs advance in level very slowly. After around five years of play, our most experienced character (a halfling) recently reached level 6. However, rather than be a source of frustration for players, the slow advancement works well, because somebody among the two dozen or so characters is always about to level up.
- The campaign world becomes more intimate, because we know who all the serious adventurers are. The stories take on an almost Arthurian quality where the unnamed knight guarding the bridge is almost bound to be somebody's long-lost kinsman. Inactive characters become the key sources for generating further quests. This makes my job much easier, because it isn't some random baron or merchant (who the players couldn't care less about) asking for help, it's Sarah the Fighter, now commandant of the fort from Horror on the Hill (B5) or Amber the Halfling who has been kidnapped and is in need of rescue.
In practice, here's what our approach looks like:
Aareck, Kaylyn, Fromo, and Star, having recently freed the village of Greenest from the schemes of a black dragon in Against the Cult of the Reptile God (N1), have now pursued Lady Mondath and her cronies across the Rushmoors and to Castle Naerytar in a chapter lifted from the 5th edition Hoard of the Dragon Queen. Atop the keep they've discovered an observatory and a strange magical apparatus that lets them see far beyond the horizon, setting the stage for more action in several other locations (including chapters from The Rise of Tiamat).
Back in Threshold, Mary the Halfling is embroiled in the machinations of vengeful merchant Clifton Caldwell and The Veiled Society (B4) along with Mitchell, Soren, Quarren, and Sayana. Their friend Amber has been kidnapped and they've been wrongly implicated in various misdeeds in the group's first real urban adventure.
Meanwhile, Amber has been sold by Veiled Society thugs to Iron Ring slavers, but managed to escape with the help of a pair of angry geese. Foiling a marauding hill giant and becoming companions with Jemma the Gnome and a blind pig named Trotter, she has been slowly making her way back toward Threshold, but not without encountering a company of sprites who need her help and who may lead her into new adventure in Beyond the Crystal Cave (UK1).
Finally, Aareck's cousin Blade and his companion Rosie have trekked high into the eastern mountains in the company of a tall, youthful stranger calling himself "Jarl" in one of the short stand-alone adventures from the Bestiary Dragons and Giants (AC10).
In the end, it turned out that Jarl was actually the son of the Cloud Giant "Blagothkus," whose castle is a base of operations for none other than Lady Mondath and her Cult of the Dragon goons (linking back up to the final chapter of Hoard of the Dragon Queen), and by helping Jarl, Blade and Rosie were able to discover a hidden entrance to the formidable fortress.
So the expanded cast lets us romp around in five separate adventures at the same time.
I remember shuffling multiple characters when playing B/X and Star Frontiers back in 5th grade, but got out of the habit in the 90s while playing games like Vampire the Masquerade, GURPs, and Pendragon.
Do other people commonly use a larger cast in their games?
