The Wonderful Wizard of Odds
A Super Hero RPG adventure set in the DC Comics Universe. The main villain of a complex casino/organized crime scheme turned out to be one of the Luck Lords of Ventura (alien scientists able to manipulate probability).
Bring in the Noise, Bring in the Flumph
D&D adventure in which a traveling band hires the PCs to defeat and capture Flumphs which, it turns out, can be used to make musical instruments of exceptional quality. A rival band is out to make sure they get the Flumphs first (Flumph are exceptionally rare on this campaign world).
Take the Mummy and Run
D&D adventure in which treasure hunting PCs search a Mummy's tomb only to find out that this supposedly wealthy noble have only a smattering of penny ante goods. The truth is that the noble was very rich and a bit nuts, having his own corpse and the removed organs gold plated. The Mummy is the treasure. Living and unliving relatives are very protective of the tomb.
Last Man Standing
Not exactly the same as the aforementioned titles, the Solomani TSS 'Last Man' is a troop transport starship that disappeared on its way back to Terra/Earth to be decommissioned. The vessel has finally been located sticking up vertically from a crater on an uncharted planet. The PCs must retrieve the 'black box' but descending from the aft engineering section down to the cockpit which is half buried in the ground. Originally run for Traveller.
Once More Into the Breach
Run in both D&D and two different superhero games (Villains & Vigilantes and M&M I think). The Breach, a character introduced earlier in the campaign has gone catatonic, resulting in time and space or planar/dimensional disturbances. The Breach's power is to travel through dimensions (or time or both) and he has obviously encountered something he couldn't handle. The PCs must enter his body, travel through the pocket dimension that is the Breach himself and save him and all the multiverse.
