I got roped into a 1e mortal game by an old friend as my first-ever RPG, though I had been interested in how they worked for years and never really had the compunction to find a group or try things out myself. It was actually a pretty solid intro, and cemented my views that every new Exalted player needs to start out playing either street-level or a mortal-prologue, simply so they have the perspective necessary to not take the rest of the game for granted.
It was a pretty laid-back affair, run somewhere between Warhammer Fantasy levels of piss-and-grit and Terry Pratchet low-key ridiculousness, given that we started off in Nexus, but the one thing my friend did which really made things Work was how he utilized the Exalted from our vantage point. We never met anyother Exalts besides Dragonblooded while we were mortal, and for good reason because when we did, they weren't so much characters but environmental scenery and walking setpieces for "crazy shit is going to happen" helping ease us into RPing as something besides passive observers.
Most other factors in those scenes took a backseat to "there is an Exalt here, work around this obstacle/keep this in mind for what you can do someday," at one point illustrated entirely by getting waylaid by bandits in the midst of an important chase on horseback, and our chaperone Earth Aspect for this particular mission decided that he would handle things while we rode off ahead and engage with the plot. Looking back from our saddles as he had been unhorsed and pushed back up against a nearby cliffside, we deeply considered turning back to rescue him, before he turned around, picked up a house-sized portion of the cliff, and windmill-slammed it into his attackers, pelting our mounts with small bits of stone and human debris from some 300 yards away. That was our challenge as mortals, not fighting the bandits, but calming our spooked horses so we could keep steady pace and not go careening off into the ravine from the aftermath of this Exalt fighting bandits.
"I... think he's got this."
It was a pretty formative experience.
