I've been at the RP game for a while. I am a male for those of you it matters to. I'm up for just about anything since one of the reasons I do this is to increase my flexibility as a writer but if you like I can slap a few basic plots down here. I won't use the ____x____ format because I don't necessarily want to imply that the characters are going to bone. Instead I will do a longer form synopsis.

Here we go.

Fantasy/Modern Fantasy

The Hunter(s):

A world where the elements of magic are naturally hostile to humanity. Hunters are the 'heroes' of this world. (Let's call it Terron) They are paid to protect people or towns from bubbles of dark magic that twist the world against the world of men. Hunters have taken this magic inside of them to turn it back. They are terribly bloodthirsty and only deemed semi-human by the common folk. Hated and feared; still they get paid. After all who would want such power turned against them.

WorldSinger

Music is connected to reality in this universe. This can be done in a sword and sorcery setting or a modern one. One of us would be the Worldsinger, a person gifted with the ability to shape reality with their voice. Just about any talented musician can create illusion or even twist fate. But the Worldsinger will re-create the world in whatever image they choose. The other will be the sworn guardian. A non-magical but incredibly skilled fighter whose only goal is to allow the Worldsinger to create the new world. The ultimate goal would likely be something like singing the original Song at a certain mystically significant location.

Death After Life

Committing suicide causes your soul to be trapped by the entity known as Death. He is in tight with Fate and you've just jumped to the front of the line. As punishment you must clean up the residue left behind my strong emotion as it does severe psychic damage to the living. I will be playing the "jumper" (name for suicide spirits) that is teaching you the rules of this new world as there is too much to explain here.

Advent

Two students at a private school are thrown together by fate as the subconscious fears and desires of every man woman and child begin to manifest as horrible monsters. Eventually we will gain the ability to control the manifestations and fight the monsters. It feels like the end of the world, but answer will be there when we dig for them.

Flowers

Has a modern option. A hero is lost in the woods. The interaction are between him (or her) and the spirit of the woods who wants the hero to stay forever.

Sci-Fi

Fool's Gold
Two (space) mercenaries are hired to help resolve a standoff involving gun-runners and the people of Heralds Court, a residential space station. The three main societies that spawned from earth are as follows.

Earthen: People who believe that technology and distance should not change who humans are. Fiercely nationalistic, they patrol the space around Earth. Many Earthen are somewhat bigoted against people who have enhanced themselves whether genetically or mechanically. Their weapons tend to be powerful but unstable.

Celestial: The Celestial's home planet is Eden IV. Their main concerns are the furthering of the human potential. There are no better modifiers of the human form. Nearly none of them retain the form they are born with. Their weapons have special effects (ex. bouncing lasers).

Taeran: Pale-haired and eyed, the Taeran are a calm people. They've the best ship technology of anyone. Mysterious and withdrawn most people know nothing of their government. Their home planet Yll is closed to non-citizens. Their weapons are the most accurate and least powerful.

Safety
The last man and woman are preserved in an inescapable fortress. Neither can remember what life was like outside the bunker. But escape is impossible with the Warden ( a gentle-mannered AI) watching their every move. The massive complex holds many secrets, but are there any answers to be found?

The Top

Two new-age gladiators fight on projected mental landscapes together in two-on-two matches. There may be hidden corruption in the story, who knows?

Normal

I don't have any plots in particular for real-world scenarios, but am totally open to everyday stories. (may update)
In any case those are just a few ideas, if you have others or would like to work together to build one I am definitely open to it. PM or thread talk is fine.
