So, here is a current consolidated list for my interest checks:

[s]-Spiral Zone (nostalgia, a 1980's action scifi cartoon, with some apocalyptic elements)

-Skeleton Warriors (more nostalgia-ish ideas, a 1990's action/scifi setting, with some fantasy and apocalyptic elements. Specifically, I would attempt a follow up to the conclusion of the series, as it left the primary antagonist dead [and the original source of the conflict destroyed], but his loyal legions still present, so continued conflict is still there, as well as a power vacuum to be filled among the villains.)

-Monster in my Pocket (a reimagining; instead of pint sized monsters running around as in the original [url=https://en.wikipedia.org/wiki/Monster_in_My_Pocket]comic and video game (among other things)[/url], the monsters of lore and fiction have died out over time. However, their spirits, their power, seems to persist. Monster hunters of one variety or another managed to capture these monster spirits, and sealed them away. One of the players would be surprised to find themselves related to one such monster hunter who has passed away, and a matter of inheritance included the stipulation that they take over safe guarding their "collection" in their place. Events take place that result in the extensive "collection", for lack of a better description... Escaping. Only one item/spirit remains, and it will have to be used to go about finding and recapturing the rest, resulting in a series of adventures where the characters willfully take on the spirit/attributes of monsters in order to fight other monsters, recapture them within their artifact vessel, and save the mortal they'd taken possession of.

-Something to do with ghosts (yet to be worked out, more like a vague interest than an actual idea)[/s]
